A liquid-air interface has a critical angle for total internal reflection of 44.3°. We assume nair = 1.00. a. Determine the index of refraction of the liquid. b. If a ray of light traveling in the liquid has an angle of incidence at the interface of 34.7°, does the refracted ray in the air make with the normal? what angle c. If a ray of light traveling in air has an angle of incidence at the interface of 34.7°, what angle does the refracted ray in the liquid make with the normal?
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.
