Assertion (A): A person standing on the land appears taller than his actual height to a fish inside a pond. (AS2)

Reason (R): Light bends away from the normal as it enters air from water.

Which of the following is correct? Explain.

a) Both A and R are true and R is the correct explanation of A.

b) Both A and R are true and R is not the correct explanation of A.

c) A is true but R is false.

d) Both A and R are false.

e) A is false but R is true.

Using refraction for plane surfaces:

n₁ = refractive index of air = 1

n₂ = refractive index of water = n

let x be the actual height of the person and y be the apparent height.

As the refractive index of water is greater than 1, therefore y is greater than x which implies that apparent height is greater than the actual height. Thus, assertion A is correct.

As light travels from denser to rarer medium, the light rays bends away from the normal due to refraction and the speed of light also changes in two mediums due to refraction. Thus, reason R is also correct . So, option A is the correct answer.
