Question

The relation between the object and image distance from the lens in terms of the focal length of the lens is called

a) fiber optics
b) lens formula
c) ohm's law
d) optical law​

Answer 1

Answer:

For a converging lens, the focal point is the point at which converging light rays cross; for a diverging lens, the focal point is the point from which diverging light rays appear to originate. The distance from the center of the lens to its focal point is called the focal length f.

Answer 2

(b) lens formula

Explanation:

1/f =1/u +1/v
