4. Water in a pond appears to be only three-quarter of
its actual depth. (a) What property of light is
responsible for this observation ? Illustrate your
answer with the help of a ray diagram. (b) How is
the refractive index of water calculated from its real
and apparent depths ?​

Answer 1

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.
