Visible spectrum Essays

Colorimeter is device which is used to measure transmittance and absorbance of light passing through a liquid sample. It is a light sensitive device. Principle: - Colorimeter works on the principle of Beer-Lambert’s Law. Beer-Lambert’s Law states that when visible light from a natural or artificial source falls on a colored homogenous medium contained in a glass container, the color of the medium is the complementary color of the light that has been absorbed by the medium. During this interaction between the

Activities for Unit IX Give definitions for the following terms: Hue refers to a particular wavelength of spectral color to which we give a name. Value refers to relative lightness or darkness from white through grays to black. Tint refers to the end color after the addition of white to a hue. The color is a lighter version of itself when white is added. Shade refers to the end color after the addition of black to a hue. The color is a darker version of itself when black is added. Intensity (also

General Description (10 marks) This video clip shows a dance by a geisha in the movie – memoirs of a geisha. It was filmed during the 1920-1930’s, the geisha culture has been in Japan since the 18th century. There is only one character performing this dance who is Sayuri. I chose to use this clip to tell you about Japan’s rich history and culture about Geishas as this clip shows a geisha’s performance and costume nicely. The long sleeves of the kimono has to be folded when performing in order to

Poetry, for me, is a release, a chance to explore complex emotions and delve into themes that go undiscussed in everyday life. Reading and analyzing writing to find a concealed meaning provides me a welcome distraction from reality. It allows me to both lose and find myself in the work. I admire and gravitate to poems that examines darker themes, but can still be enjoyed purely for their lyrical language. For these reasons, I am fond of Sylvia Plath’s poem, “Tulips”, due to the disparity between

Every organism in the universe requires water for its survival. Arguing out that water is good or bad is inconclusive. Water for human consumption is supposed to be subjected to quality tests so as to determine its safety for consumption and usage. A number of water sources around the globe suffer from some form of impurities. This makes it unsafe and unhealthy for individuals to use it. Challenges such as unsafe water, insufficient or the lack of quality healthy water has been an issue which has

United Kingdom Flag [Paragraph 1] The UK flag has three colors; red, white and blue within a combination of red crosses with white edges and a blue background. White stripes edge the front red cross which is superimposed onto another red diagonal cross. The two red crosses align proportionally on top of the blue field which has a white saltire. The flag, also known as the “Union Flag” and also nicknamed “Union Jack”. Union Flag’s standard height to length ratio is 1:2, however, the war flag variant

1. The clinical macula is smaller in area than the anatomical macula. The clinical macula appears as a small and fuzzy dark spot and can be distinguished through the pupil by clinical observation with an ophthalmoscope. The anatomical macula is not distinguishable through an ophthalmoscope as it is defined histologically; that is in terms of having two or more layers of ganglion cells. The anatomical macula is larger and encloses the clinical macula. 3. This would be the structural characteristic

1.The transmitted light that was produced by the flashlight differs in terms of how much solution that was present in a test tube. Given the 5 test tubes, dye solution had the least transmitted light. It had the least transmitted light because the more molecules that is present in a container, the harder the light can pass through. Absorbance is the reason why light had to interact with a lot of molecule that is present in the dye solution. Unlike the clear water light can pass through easily because

two categories; colours produced through pigmentation, and those produced through structural means, with considerable overlap occurring between the two. Pigmentation is achieved through the absorption of particular wavelengths of visible light (the wavelengths visible light being between 380 and 750nm) by chromophores, regions of organic molecules responsible for colour. The wavelengths that are not absorbed by chromophores are consequently reflected, resulting in the distinctive colour of the

Detection and Purification A Monascus pigments is a complex of azaphilone compounds, which can be separated by using various analytical techniques. UV- Visible spectrophotometric methods The UV-Visible spectrophotometric method is usually used for the confirmation of pigments produced by Monascus with taking absorbance at a respective wavelength. i.e. Yellow pigment at 400, Orange 470, and Red at 500 nm. The pure solvent or extract of unfermented substrate was always used as the blank (Carels and

The color expresses and affects moods and emotions. The colors may be dark, light, bright, warm or cold. Colors in films usually have positive or negative connotations. In Romeo and Juliet there were a lot of bright colors in their clothing, cars and settings (such as the theme park, with colorful, bright colored rides etc.). the main characters in the film also portray a certain color, Juliet is the light (good girl) and Romeo is the dark (bad boy). When Romeo and Juliet were separated by the big

Maria Sanchez Professor Heaslip ATCM 3301.004 28 February 2023 Absent parents, a lone child About 3 million children in the United States are being raised by grandparents according to Wbur reports, which means some of them to have a vastly different childhood from the rest. The Red Balloon is a masterpiece of simplicity, a unique short film directed by Albert Lamorisse in 1957. Considered one of the best short films, and winner of an Oscar for Best Original Screenplay for its special story about

What is light? It is an electromagnetic radiation that is visible to the human eye, and is responsible for the sense of sight. (slideshare, 2014) Light is part of the electromagnetic spectrum, which ranges from radio waves to gamma rays. (Andor, n.d.) The wave theory of light A Dutch astronomer, Christian Huygens, developed the wave theory of light in the late 1600s. In this theory, he thought of light as a longitudinal wave. This theory states that light is emitted in a series of waves that spread

How have humans used visible and invisible kinds of light to see inside the human body? Introduction With technology changing every single day, scientists are finding new was to look inside of the human body. There are many methods all ready that scientists can use to look inside of the human body. After the discovery of X-ray, scientists have developed many new ways to see inside the human body. They are X-rays, MRI, Ct scans and laser treatment but some of these don't use light, so I am only going

The Refraction of Light Waves: The bending of light is known as Refraction. When light travels from a optical less dense media such as air into a dense media such as glass,light will refract/bend towards the normal line and the speed and wavelength of the light will decrease. When light travels from a optical dense media into a less optically dense media, light will refract/bend away from the normal as it exits the dense medium.The speed and wavelength of the light will increase. When closely observed

The amount of refraction a light wave experiences is expressed by the difference between the angle of refraction and the angle of incidence. The light wave traveling to the boundary at an angle of incidence of 45 degrees for example will refract towards the normal because the medium it is now travelling through ( water, glass, diamond ) is more optically dense than the first medium ( air ). Below is a diagram of a light wave approaching three boundaries at an angle of 45 degrees. The medium is different

Introduction Circular dichroism (CD) is form of light absorption spectroscopy that measures the difference in absorbance of right- and left-circularly polarized light (rather than the commonly used absorbance of isotropic light) by a substance. It is applicable for molecules have one or more chiral chromophores [1]. Circular dichroism = ΔA(λ) = A(λ)LCPL - A(λ)RCPL, where λ is the wavelength This technique measured a molecule over a range of wavelengths. All chiral molecules can be studied, particularly

developing children, these changes and the rate at which the brain develops are very different in children with autism spectrum disorders. As a result of these differences, over 96% of children with autism spectrum disorders (ASD) exhibit atypical behavioural responses to sensory information report sensitivities in multiple sensory disciplines. Comparable to the wide-range of spectrum severity that is seen in the

Jonathan, a seven and a half year old boy is a social second grader who has normal intelligence. However, Jonathan was diagnosed with spastic cerebral palsy and has dysarthric speech patterns. With spastic cerebral palsy, Jonathan has difficulty regarding his motor control and movement. Confined to his wheelchair, Jonathan works independently, separate from his classmates. Jonathan cannot produce clear speech, his dysarthric speech pattern prevents him from speaking freely in the classroom and

It not so much only the fact that within the story people cannot communicate with each other because of the different language they speak, but it becomes clear how much effect prejudices have on people. Juan Pellicer calls this “a Babelian syndrome: broken communication, misunderstandings, isolation both on the global level as well as in the intimate realm of relations between children and parents, particularly with the consequences of separation and deafness” (Pellicer 240). People are so used to
