Question

if 5 m tall object is placed at a distance of 30 cm from a convex mirror of focal length 15cm find the position size and the nature of the image formed

Answer 1

h=5m=500cm

u=-30cm

f=15cm

1/15=1/v+1/-30

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

1/v=-30-15/-450

v=-450/-45=10cm

Position=+10cm

h'/h=-v/u

h'/500=-10/-30

h'=-5000/-30

h'=166.67cm

Size=166.67cm

Nature:virtual erect and diminished
