(b)Change in shape of the sun during sunrise and at noon
(c)Both (a) and (b)
(d)Neither (a) nor (b)

Answer 1

Answer:

a. is the right option

Explanation:

When the sun is slightly below the horizon the light which is coming from the sun travels from less dense to more dense air and refracted downwards. That is why, the sun appears to be raised and can be seen before 2 minutes of the actual sunrise and after 2 minutes of the actual sunset.

It occurs due to atmospheric refraction.

means early sunrise and late sunset

Answer 2

(c) Both (a) and (b) is depicted by the picture.

• When the sun rises, it is visible to inhabitants of Earth two minutes earlier. Similarly, the setting sun is also visible two minutes after the sun is set.
• Moreover, the change in shape in the afternoon in comparison to morning and evening is due to the same phenomenon.
• The phenomenon responsible for the above occurrences is the refraction of light.
• At noon sun is directly above our head, thus refraction does not occur. But during sunrise and sunset, the light gets refracted changing the position and shape of the sun.
