Question

An object is placed at a distance of 15cm from a convex mirrior of focal length 30cm. find the position and the nature of the image?

Answer 1

m= 0.6
so the image is smaller in size , virtual and erect.

Answer 2

hello friend

u=-15cm
f=30cm
v=?
using mirrors formula
=}1/f =1/v+1/u

=}1/30=1/v-1/15

=}1/30+1/15=1/v

=}3/30=1/v

=}1/10=1/v

=}v=10cm
nature of image = virtual and erect
