Question

A spherical mirror produces a magnification of (-1). Find the position of the object and

the image.​

Answer 1

1) It is a concave mirror.

2) m= -1 , U= -50cm

m= -V/U

Therefore,

-1= -V/-50

=> V= -50cm

3) 1/V+1/U=1/f

=> 1/-50+1/-50=1/f

=> 1/-25=1/f

Therefore f= -25cm

Hope this helps:)
