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.
