Question

Quizplus · Accepted Answer

The solar radiation curve is a graph that shows the distribution of the radiant energy emitted by the sun as a function of its frequency or wavelength. It is commonly plotted as the brightness of sunlight versus its frequency, which results in a curve that peaks in the visible range and drops off rapidly in both the ultraviolet and infrared ranges.
