Which of the following quantities increase when wavelength of light is increased? Consider only the magniutude

A

The power of a converging lens

B

The focal length of a converging lens

C

The power of a diverging lens

D

The focal length of a diverging lens

Text Solution

Verified by Experts

The correct Answer is:
B, D
(b,d) With increase in wavelength, refractive index gets decreased. Therefore, focal length of lens will be increased.
