Question

the power of convex mirror of focal length 50 cm is​

Answer 1

Answer:

Convex (So Focal length is positive)

Given : f = +50 cm or +50 x 10^-2 m

To Find : P = ?

Formula : P = 1/f

P = 1/50 x 10^-2

P = 100/50

P = 2

Answer 2

If parallel rays of light fall on a convex lens they converge when passing through and meet at a point on the other side. That's why the convex lens is known as a converging lens.

$P=\frac{1}{f(in)} =\frac{1}{\frac{50}{100} }$

$=+2D$
