A large container holds two layers of liquid: a 10.0 cm thick layer of vegetable oil (ρ = 920 kg/m3 , n = 1.47) above a 20.0 cm thick layer of water (ρ = 1000 kg/m3, n = 1.33). There is air (ρ = 1.20 kg/m3, n = 1.0003) above the oil layer. Nia holds a red laser which emits 632.8 nm light to the right and down, so that the ray makes an angle of 50.0° relative to a line normal to the oil layer. a) What is the angle of reflection at the oil→ water interface? ________________________ b) What is the angle of refraction at the oil→ water interface? ________________________ c) What is the frequency of the light in the air?________________________
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.

f) Nia looks into the tank and sees where the laser light impinges on the bottom of the container. She names this point A. She also sees the point where the laser light enters the oil layer and names that point B. The point on the bottom of the container directly below point B she names point C. What is thedistance between points A and C?________________________
