Solution

The correct option is D Violet

The refractive index of the medium is maximum for the violet light and minimum for the red light. Therefore, when white light enters a prism, it disperses into seven constituent colours and violet light shows the maximum deviation.

Q. Which colour of light is most refracted during dispersion by a prism?

Statement 1: When a 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 a different angle.
