Question
Describe how the duration of sunlight changes from the Equator to the Poles with respect to the angle of incidence.
Solution
As the angle of incidence changes from 0° to 90° from Poles towards the Equator; So the duration of sunlight also changes. The duration of daylight is 12 hours on the equator and 24 hours on the North Pole in summer and 24 hours on the South Pole in winter. So the duration of sunlight increases from the Equator to the North Pole and decrease in the winter season and vice-versa in between Equator and South Pole.
