relating the angle of insolation and direct light received by surface\nwhich angle allows the soil to receive the most direct light from the lamp?\n0 degrees\n20 degrees\n45 degrees\n90 degrees
Answer
Brief Explanations:
When the angle of insolation (angle between the incoming light - source rays and the surface normal) is 90 degrees, the surface is perpendicular to the light - source rays. This results in the most concentrated and direct light received by the surface. As the angle deviates from 90 degrees, the light is spread over a larger area on the surface, reducing the intensity of direct light.
Answer:
90 degrees
