Question

Power of lens +1.75d. Find the focal length of lens. Is the lens diverging or converging

Answer 1

A lens formula may be defined as the formula which gives the relationship between the distance of image (v), distance of object (u), and the focal length (f) of the lens.

If the light rays converge (as in a converging lens), then they will converge to a point. This point is known as the focal point of the converging lens. If the light rays diverge (as in a diverging lens), then the diverging rays can be traced backwards until they intersect at a point.

So,it is converging.

Answer 2

Answer:

Its converging...........
