Question

During which period of the day the Sun’s rays make the highest angle of incidence?

Options

• Morning

• Noon

• Afternoon

• Evening

Answer 1

Noon

Short explanation:

During noon, the Sun’s rays make the highest angle of incidence, meaning they strike the Earth’s surface most directly and concentrated over a smaller area. This causes maximum insolation and the highest temperature during this time of the day. In the morning and evening, the Sun’s rays are more slanting, spreading over a larger area and causing lower temperatures.
