Answer:
Explanation:power of the lens= +1.5D
Using P=100/f
f=100/p
f=100/1.5
=1000/15= 66.67m
As the focal length is positive, it is convex lens.
Hence, It is a converging lens.

Answer:
Given : power = 1.5 dioptre
f=?
Explanation:
Since the power is positive it is a conves lens. hence it is converging lens.
p=1/f or f=1/p
f=1/1.5
=10/15
=o.666
f=0.67
