Question

an object is placed at a distance of 6M in front of convex mirror of focal length 9 CM calculate the position and magnification of the image and state its nature​

Answer 1

Explanation:

U = -6cm, f = 12 cm, v = ?

We know that

1/v + 1/u = 1/f

⇒ 1/v + 1/-6 = 1/12

⇒ 1/v = 1/12 + 1/6 = 3/12 = 1/4

∴ v = 4 cm
