2. In the image below, an incident ray shines at an angle onto two layers of class. The first layer has an index of refraction of 1.47. The second layer is of an unknown index. You have determined the point at which the ray exits the second layer of glass. You will need a protractor to measure angles in this problem. (A) Determine the angle of refraction of the ray inside the first material. (B) Trace the path of the ray through the first and second layers of materials on the picture below. (C) Determine the unknown index of refraction in the second material. (D) Determine direction of and draw the path of the ray after it exits the second layer.
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.
