Question

An object is placed at 30cm in front of a convex mirror of focal length 10 cm. Find out the distance of image from mirror.​

Answer 1

Answer:

       v = 15cm

Explanation:

u = 30cm

f = 10cm

v = image distance

1 / v + 1 / u = 1 / f

1/v + 1/30 = 1/10

1/v = 1/10 - 1/30

1/v = 3/30 - 1/30

1/v = 3 - 1 / 30

1/v = 2/30

1/v = 1/15

v = 15cm
