A light ray having a combination of three colours of wavelengths, 2,, Ag, and Ac, is incident on one face of a glass prism having indices of refractions of, na, Ng, and nc, respectively. The three rays of colors emerge from the opposite face of the prism at different angles, as shown in the figure below. Which of the following is true about the speed of light of the three colours inside the glass? AB Glass prism Combined three colors v_B < v_A < v_C
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.
