Question

Janaki observed that light is travelling from water to crown glass. The refractive indices of these two are given below. Water: n = 1.33, Crown glass: n = 1.52 Now answer the following:
a) Which is the denser medium and which is the rarer medium?
b) What happens when light travels from Crown glass to water?

Answer 1

a. crown glass is denser medium and water is rearer medium.
b. when light travels through crown glass to water the refraction property is observed where crown appears to be slightly bending in water but in reality it remains there.
