The intensity of sunlight from the Sun follows an inverse-square law. Therefore, if Earth were two times farther the Sun, for example, Earth would receive only one-quarter of the amount of sunlight.
An inverse-square law is a law stating that a physical quantity is inversely proportional to the square of the distance from the source of the physical quantity. In general, any point source that spreads its influence equally in all directions without a limit to its range will obey the inverse-square law.
The Sun is a sphere, so the intensity of its radiation (light) obeys the inverse-square law. This can be mathematically expressed as [tex]I=\frac{S}{4\pi r^2}[/tex].
