Question

1.An object 5.0 cm in length is placed at a distance of 10cm from a convex mirror of radius of curvature 150cm. Find

the position, nature and size of the image.

Answer 1

Here,

height of object=5cm

f=15 cm

u=-20cm

therefore,

1/v=1/f-1/u

=1/15+1/20

=7/60

so v =60/7

therefore height of image=60/7/20=3/7

so the image is virtual,erect and smaller in size by 3/7th of its original size
