Question

Four locations on Earth receive sunlight at different angles. At which of the following angles will the intensity of sunlight received be the greatest?

a) 500

b) 90°

c) 750

d) 25°

Answer 1

The greatest intensity of sunlight is received when it strikes the surface at a 90° angle because the sunlight is concentrated over a smaller area, resulting in a higher intensity.

Step-by-step explanation:

The intensity of sunlight received on Earth depends on the angle at which it strikes the surface. The greatest intensity of sunlight is received when it strikes the surface at a 90° angle, which is perpendicular to the surface. At this angle, the sunlight is concentrated over a smaller area, resulting in a higher intensity. Therefore, option b) 90° will have the greatest intensity of sunlight received.
