a doctor has prescribed a corrective lens of power 1.5D .find the focal length of this lens.is the prescribed lens converging or diverging
Answered by admin @
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.
