Question

Four locations on Earth receive sunlight at different angles. At which of the following angles will the intensity of sunlight received be the least? 90° 75° 50° 25°

Answer 1

25°

Step-by-step explanation:

The intensity of solar reaches the earth with greater intensity when the sun is in a position that allows the sun's rays to reach the earth at right angles. This is possible when the sun is well above the earth, at a 90º angle. The farther from this angle, the lower the intensity of the sun's rays on the earth, in that house, when the sun is at 25 ° the intensity of the sunlight received will be less.

Answer 2

25°

Step-by-step explanation:

The Intensity of sunlight is greatest when the sun is overhead, that is when the sun is directly above, thus the rays strike the surface at right angles. In this way the intensity of sunlight will be concentrated over a smaller region compared to when the rays strike the surface at a much smaller angle like 25 degree.
