Question

Tree is placed 15cm from a converging mirror of radius curvature 20cm. The distance of the image

Answer 1

Answer:

distance between object and mirror (u) = 15cm

radius curvature = 20cm

focal length (f) = 20 /2 = 10cm

distance between image and mirror(v) = ?

formula for mirror -

1/f= 1/v+1/u

put the value :- 1/10 = 1/v + 1/15

1/v = 1/10 - 1/15 = 3- 2/30 = 1/30

v = 30cm
