Answer:
Inverse square law
Explanation:
According to inverse square law, a variable y is inversely proportional to the square of another variable x. Therefore, expressed as
[tex]y=\frac {k}{x^{2}}[/tex]
Where k is constant of proportionality.
Taking an example when x is diatance then the phenomenon described in the question will perfectly fit the inverse square law.
In conclusion, the phenomenon described fits the inverse square law.
