Question

Assertion (A): The sun looks reddish during sunrise and sunset.
Reason (R): The sun is directly overhead at noon and the sunlight has to trave
relatively shorter distance.​

Answer 1

Answer:

Both a and r are correct but r is not the correct explanation of assertion.

Answer 2

Assertion and Reason are true and the assertion is the correct explanation of reason regarding the colour of sunrise and sunset.

• The phenomenon occurs due to the scattering of light. Due to the large wavelength, the red light scatters least while blue light due to the shorter wavelength scatters away.
• This further happens because during sunrise and sunset sun is at a farther distance while at noon sun is directly overhead, causing the light to travel less distance.
• Thus sunrise and sunset appear reddish.
