Question

State whether the following statement is True or False.

White light is polychromatic light and has all the seven wavebands present in it.

Answer 1

This statement is true.

Explanation:

• White light is composed of seven colours (VIBGYOR), so it is polychromatic light.
• When all the seven wavebands excite the retina together, the brain perceives the colour as white.
• Hence, white light contains all the seven wavebands.
