Question

A spherical mirror produces a magnification of -1 on a screen placed at a distance of 50 cm from the mirror find distance of image and focal length of mirror Pleease help me i will follow you and make branliest. Please no scam.

Answer 1

Answer:

The magnification of the spherical mirror -   [-1]

Distance between the mirror and screen -  50 cm

So;

So , the mirror is a concave mirror ;

calculating the distance of the image ;

m = -v/u = -1 ,

Then ; u = v = -50cm

Therefore distance = [u] + [v] = 100cm.

Focal length of the mirror ;

1/f = 1/v + 1/u

1/-50 + 1/-50 = -1/25 is therefore the focal length of the mirror.
