Question

An object 10 cm high is placed at a distance of 15 cm from a convex lens of focal length 12 cm. Determine the position, nature magnification and height of the image​

Answer 1

Answer:

1/f=1/v-1/u

1/u=1/v-1/f

=(-1/15)-(-1/12)

=(-4/60)-(-5/60)

= 1/60

u=60cm

m=v/u

=15/60

=1/4

=0.25

0.25=h'/h

=h'/10

h'=.25*10

= 2.5 cm
