My teacher ask us to do this experiment At the middle of a paper protractor, set a crown glass plate. Shine a laser pointer on the side of the glass plate. After that, identify the normal to the incident ray. Then, measure the angle of refraction of each of the following angles of incidence: 10°, 15°, 20°, 25°, 30°, 35°. On a graph, plot the sine of the angle of incidence (x-axis) versus the sine of the angle of refraction (y-axis). Using this graph, identify the refractive index of glass and compute the percentage error of the index of refraction. but I cannot understand it. would u kindly help me understand the step by step process? I'm a visual learner so sketch it
Refraction of Light
Refraction is a change in the direction of light rays when they travel from one medium to another. It is the bending of light when it goes through different media.
Angle of Refraction
Light is considered by many scientists to have dual nature, both particle nature and wave nature. First, Particle nature is one in which we consider a stream of packets of energy called photons. Second, Wave nature is considering light as electromagnetic radiation whereas part of it is perceived by humans. Visible spectrum defined by humans lies in a range of 400 to 700 nm wavelengths.
Index of Refraction of Diamond
Diamond, the world’s hardest naturally occurring material and mineral known, is a solid form of the element carbon. The atoms are arranged in a crystal structure called diamond cubic. They exist in a huge variety of colours. Also, they are one of the best conductors of heat and have a very high melting point.
