Question

An object 5cm in height is placed at a distance
from a convex mirror of focal length 12cm
find the nature position and size of the
of 20cm​

Answer 1

Answer:

h = 5cm , u = -20 cm , f = 12 cm

1/v + 1/u = 1/f

1/v = 1/f - 1/u

= 1/12 - 1/-20

= 1/12 + 1/20

= 5 + 3/60

= 8/60

v = 60/8

v = 7.5 cm
