Question

An object is placed at a distance of 15 cm in front of a convex mirror of focal length 12 cm. Find the position of the image ​

Answer 1

Explanation:

distance of the object(u)=15cm

focal length (f)=12cm

distance of the image(v)=?

using mirror equation,

1/v+1/u=1/f

1/v=1/12-1/15

=15-12/180

=3/180

1/v=1/60

v=60cm
