Essay On Angle Of Reflection

1222 Words5 Pages

Aim:

To investigate the effect of angle of incidence on angle of reflection

Background Information

Light reflection happens when the light hits a smooth and shiny object like glass and mirror. Light wave is also called transverse wave. Light passes through the medium. The light bends and refracts. Here are some examples of light reflections. The mirror reflection works when the light hits the mirror and reflects on the other side. (Bbc.co.uk, 2017) The normal is the middle of the light and the reflected light. The specular reflection is almost the same as the normal light reflection but this time it travels in a bigger light.(YouTube, 2017) The diffuse reflection is when the light hits a rough surface like wood or any material that straight.(Physicsclassroom.com, …show more content…

(Hub, 2017)

I wanted to investigate reflections further so I know the different kinds of reflections. The materials that I will be using for this experiment is the light box which will be provided in the science laboratory. I chose to use the light box for this experiment because it’s the materials that are best to use in this experiment.(YouTube, 2017) The five different angles of incidence that will be changed is ( 20°, 30°, 40°, 50°, 60°). The angle of incidence = angle of reflection is called the law of reflection. I chose this five angle of incidence because I thought that this angles will be the best for the experiment because it’s all next together.

Hypothesis

I predict that if the angle of incidence is bigger, the angle of reflection will be the same as the angle of reflection. For example, if the light is bright it will have faster reflection because if the light isn’t bright enough it will have a possibility that it wouldn’t even reflect.

Variables

Independent variable

Angle of incidence ( 20°, 30°, 40°, 50°, 60°)

Dependent variable

Angle of reflection

    Unit D Summary: Light and Geometric Optics 10.1 : Light and The Electromagnetic Spectrum Chapter 10.1 covers light and the electromagnetic spectrum. This chapter starts off by describing how light is a form of energy that travels in waves. The properties of said waves include a crest (the highest point of the wave), the trough (the lowest point of the wave), and the rest position (the level of a wave without energy).

    Everyone needs to struggle in order to preform better. Writing has always been a strength of mine, but I found it a challenge to move from the high school, six-paragraph essay format that I had grown accustomed to. Throught the course of this semester, I was able to acquire many different skills in ENG 1101 that have helped me transition into more complex writing. These include various writing techniques, MLA formatting, writing for purpose, convincing my arguments and finding and properly using sources. The portfolio I have submitted is comprised of three works of writing that I completed for ENG 1101 over the last three months.

    CULTIVATING REFLECTION-IN-ACTION & REFLECTION-ON-ACTION Reflection is loosely defined as the way we learn from an experience in order to understand and develop practice. Reflection is a means of processing thoughts and feelings about an incident, and gives us a chance to come to terms with our thoughts and feelings about it. For example, if something did not go the way you wanted it, we would tend to reflect on it by asking ourselves questions such as why did it go wrong and how did it go wrong. John Dewey’s theory of Reflective Practice John Dewey (1933) was among the first to identify reflection as a specialised form of thinking.

    M.H. Abrams’s The Mirror and the Lamp: romantic theories and the critical traditions is one of the most influential books in the field of western criticism. It was published in the year of 1953. The title of the book refers to the two contradictory metaphors used to portray the artist – one comparing the artist to a mirror which reflects nature as it is or perfected whereas the other compares the artist to a lamp that illuminates the object under consideration. Professor Abrams in his book illustrates the transition of the perspective of the theorists on the artist from one to the other and the ramifications of the latter in aesthetics, poetics and practical criticism. The essay “Orientation of critical theories” is the first chapter of this book.
