Question

water in a pond appears to be only three quarter of its actual depth what property of light is responsible for this observation illustrate your answer with the help of a diagram how is the refractive index of water calculated from its real depth and Apparent depth

Answer 1

Hey mate here is your answer

Water in pond appears to be only three quarter of it's real depth. This is due to refraction of light when it enters into water, and refracted back in air then it bend away form normal and we see the level of water to be risen.
Formula. Real depth upon apparent depth
I hope my answer helps you☺☺☺

Plz mark my answer as brainlist

Have a good day

Answer 2

Answer:

This is due to refraction of light

Explanation:

When we look into water the ray from actual depth reaches our eye but we get a feeling that it is coming from 3/4th depth of water .So, water in a pond appears to be only three quater of it's depth
