Immiscible liquids (ones that do not mix) can be placed on top of each other in a glass. Each layer may have a different refractive index. PING PONG BALL LAMP OIL RUBBING ALCOHOL SODA CAP BEADS VEGETABLE OIL WATER CHERRY TOMATO DISH SOAP If we shine a ray down from the air above into the glass on the left at an angle of 3.8 degrees from the vertical, what is the angle of the light when it reaches the bottom of the glass?

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.
