Question

An object has height 3cm. Its erect image is obtained when placed in front of a convex lens. If its magnification is 2, what is the height of the image?​

Answer 1

Explanation:

Object height (h) = 3cm

Magnificaton(m) = 2

We know that,

⇒ m = h/h₂

⇒ 2 = 3/h₂

∴h₂ = 3/2

      = 1.5 cm
