Question

Assertion (A): The colour of clear sky appears blue.

Reason (R): Light of blue colour has longer wavelength as compared to the light of red colour. So, it is scattered more in the upper atmosphere.

Options

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

• Both (A) and (R) are true, but (R) is not the correct explanation of (A).

• (A) is true, but (R) is false.

• (A) is false, but (R) is true.

Answer 1

(A) is true, but (R) is false.

Explanation:

The claim is true and can be backed up by science facts about Rayleigh scattering. The reason is wrong because it gives the wrong information about the blue and red light colours.
