Question

(d) A water pond appears 3m deep. If the refractive
ractive index of water is 4/3 , find the actual depth of
the pond.
​

Answer 1

Use the shift formula,

Shift = t • [ 1 - ( 1/mu )] = 3 • 1/4 = 3/4 m deep.

Answer 2

Answer:

4 m

Explanation:

Refractive Index = Real Depth/ Apparent Depth

So,

Real Depth = Refractive Index × Apparent Depth

ie.

Real Depth = 4/3 × 3m

= 4 m

So Real Depth of Pond is 4 m.
