As shown in the figure below, a light ray is incident normal to one face of a 30°-60°-90° block of crown glass that is immersed in carbon disulfide. 60.00 30.0% (a) Determine the exit angle 0, of the ray. 35.8 Your response differs from the correct answer by more than 10%. Double check your calculations.° (b) A substance is dissolved in the carbon disulfide to increase the index of refraction n,. At what value of n, does total internal reflection cease at point P? 1.44 Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error.
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.
