Answers

Answered by vnikhithareddy06

4

Answer:

Hi there!

The lens will be a concave lens because the power is negative.

Explanation:

P = 100/f (in cm)

-4 = 100/f

f = -25 cm.

We know that the focal length of a concave lens will be negative.

Therefore, the answer is concave lens.

Hope it helps!
