Solution

The correct option is A
Voilet

Violet color deviates the most. This is because Violet has the least velocity in the spectrum and therefore undergoes maximum refraction. Red deviates the least as it has the highest velocity.

Statement 1: When white light ray passes through a prism it disperses into seven different colours, and this phenomenon is called dispersion.

Statement 2: Refraction depends upon the wavelength of light and since different colours have different wavelengths, they are refracted at different angles and so they are split into the colour spectrum.

A ray of white light is passed through a glass prism and spectrum is obtained on a screen.
