Question

A spherical mirror produces an image of magnification -1 on a screen placed at a distance of 50 cm from the mirror. Find the distance of the image from the object.

Answer 1

image is formed on a screen and m= -1 means image is real and inverted.

v= -50 cm

m= -v/u

u= -v/m = -(-50)/-1 = 50/-1 = -50cm

distance of image from object= v-u = -50-(-50)= 0cm
