Question

An object is placed at 20cm infront of a convex mirror of focal length 10cm.Find the position and nature of the image .​

Answer 1

Answer:

By1/f=1/u+1/v

1/−10=1/20+1/v

1/v=-3/20

So, v=−6.67cm

The image is behind the mirror and virtual.

By m=|v/u|

m=6.67/20

m=0.33<1(smaller than object)

Hope it helps.
