Answer:

A doctor has prescribed are corrective lens of power 1.5 D . Find the focal length of this lens. Is the the principled lens diverging or covering lens​?

Focal length=0.67 m

Converging Lens

Explanation:

f=1/P

where f=focal length and P=power of the lens

so, f=1/+1.5

     f=+0.67 m

As, focal length is in positive, it is a converging lens.
