Answer:
Power, P= ff =1.5
=1.5 f=0.67 m
=1.5 f=0.67 mSince, focal length is positive it is a convex lens i.e. converging lens.

Given
P = +1.5 D
Find out
We need to find out the focal length of the given lens
Solution
We know that
f = 1/P
Where,
f is focal length
P is power
f = 1/P
= 1/+1.5 = 0.67 m.
As the power of lens is (+ve), the lens is a converging lens.
