  • Colorimeter Lab Report

    1015 Words  | 5 Pages

    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

  • Sylvia Plath's Poem 'Tulips'

    1123 Words  | 5 Pages

    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

  • The Importance Of Water In Long Island

    1411 Words  | 6 Pages

    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

  • Clinical Macula Case Study

    883 Words  | 4 Pages

    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

  • Romeo And Juliet Color Analysis

    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

  • Column Chromatography Essay

    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

  • Light Theory Of Light Essay

    810 Words  | 4 Pages

    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

  • Reflection: The Refraction Of Light Waves

    969 Words  | 4 Pages

    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

  • Essay On Chromatic Aberration

    1283 Words  | 6 Pages

    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

  • Circular Dichroism

    994 Words  | 4 Pages

    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

    of autism. In the United States it is estimated that 1 in 68 children are diagnosed with autism, about 1 in 42 boys and 1 in 189 girls are estimated to have this disorder (What is Autism?, 2018). When a child is diagnosed with autism or autism spectrum disorder, it means that the child is having challenges and difficulties with their “social skills, repetitive behaviors, speech and nonverbal communication, as well as by unique strengths and differences” (What is Autism?, 2018). There are many

  • Speech Therapy Abstract

    1023 Words  | 5 Pages

    Abstract— Speech disorder refers to difficulties in producing vocal sounds or problems related to voice quality. Cases of speech disorders in children and adults have increased manifold, but speech therapists are still hard to be found. An automatic human-machine interface (HMI) is the need of the hour. The proposed system provides a real time feedback to the person with the disorder, which helps them detect mistakes in their speech and rectify them. The HMI incorporates the concept of speech recognition

  • Cerebral Palsy

    “Cerebral palsy is a physical impairment that affects the development of movement. Impairment can vary considerably and no two people with cerebral palsy are affected in exactly the same way. The problems that children and adults with cerebral palsy face, including discrimination, are often similar” (Rosenbaum, 2003).Cerebral palsy can identified as an impairment that prevents the muscles from doing what it is supposed to do. Children with cerebral palsy often have problems that include muscle weakness

  • Autism Persuasive Speech

    Imagine being viewed by the world as different. Wouldn’t you want the people around you to understand? A 12-year-old boy diagnosed with autism was told he was not equal to his classmates. He had a hard time identifying social cues and a difficult time speaking, thus he was labeled “weird” and “an outsider”. The young boy did not like the way he was feeling or being treated so he decided to do something about it. He knew his peers did not know or understand anything about the subject of Autism

    Autism refers to a disability defined by demonstration of certain types of behaviours and patterns of interaction and communication. It is a profound and poorly understood developmental disability that severely impairs the individual’s ability in the areas of language and social relations. Autism belongs to a group of disorders identified by the Diagnostic and Statistical Manual Fourth Edition (IV) published in 1994 as Pervasive Developmental Disorders (PDDs). Autistic children are normal in appearance

    disorder came to the forefront some 70 years ago, but its prevalence and frequency as a diagnosed condition has increased more recently. Because many syndromes and other related conditions comprise the commonly known “spectrum,” addressing autism can be a challenge. “Autism spectrum disorder (ASD) and autism are both general terms for a group of complex disorders of brain development. They include Rett Syndrome, childhood disintegrative disorder, pervasive developmental-disorder- not otherwise specified
