Question

In a pond of water, a flame is held 2 m above the surface of the water. A fish is at depth of 4 m from the water surface. Refractive index of water is 4 3 . The apparent height of the flame from the eyes of fish is -, 5 . 5 m, 6 m, 8 3 m, 20 3 m

MARKS App · Accepted Answer

Apparent height of flame above water surface. h ′ = μ h = 4 3 × 2 = 8 3 m Therefore, apparent height of the flame from the eye of fish = d + h ′ = 4 + 8 3 = 20 3 m
