Question

A person standing on the river Bank. The person appears to the fish inside the water as

A)taller. B)shorter. C) original height
D)depends on fish

Answer 1

taller because of refraction

Answer 2

Option A is right. The person appears taller.

• The reason is refraction.
• Refraction is the change in the path of the light wave when it travels from one medium to the other.
• The speed of light will be different in different media.
• This change in velocity is the reason for refraction.
• Water is a denser medium when compared to the air.
• When light travels from a denser medium to a lighter medium, it moves away from the normal.
• So the image formed in the rarer medium appears to be larger
