• A. True
• B. False

Answer 1

The correct option is A

True

Dispersion of light can be defined as the splitting of a visible light beam into its constituent colours. Red, orange, yellow, green, blue, indigo and violet colours are obtained when a white light beam is dispersed. Dispersion of light happens when a light beam passes through a dispersive medium such as a prism and undergoes refraction. A rainbow is formed when the light is dispersed through raindrops.
