White light is incident on a diffraction grating. What color is the central maximum of the interference pattern?

The color of the central maximum is white.

Explanation:

A diffraction grating in optics is generally known as an optical component that contains a periodic structure. It is commonly used to breakdown and diffract light into different beams that move in several directions. For example, if a light ray is allowed to pass through the component (i. e. diffraction grating), the central maximum will have a white color.
