The law is called The Inverse Square Law .
inversely
Newton's Law of Universal Gravitation states that the force of gravity directly proportional to product of the two masses&inversely proportional to square of the distance between them
Graham's law states that the rate of effusion of a gas is inversely proportional to the square root of its molecular weight.Graham's law states that the rate of effusion of a gas is inversely proportional to the square root of its molecular weight.
Coulomb's law states that the force between two charged particles is directly proportional to the product of their charges and inversely proportional to the square of the distance between them. Mathematically, it is represented as F = k * (q1 * q2) / r^2, where F is the force, k is the proportionality constant, q1 and q2 are the charges, and r is the distance between the charges.
Apparent Brightness = luminosity/4(pi)x(distance)^2
Newton's Law of Universal Gravitation states that two bodies in the universe attract each other with a direct proportional force and inversely proportional to the square distance between them.
The Law of Universal Gravitation is derived from observations by Isaac newton, called induction. It states that, "Any two bodies in the universe attract each other with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them."
molar mass
The law of universal gravitation states every object in the universe attracts every other object, the attraction being proportional to the product of their masses and inversely proportional to the square of the distance between them.
Graham's law of effusion states that the rate of effusion of a gas is inversely proportional to the square root of its molar mass. In other words, lighter gases effuse or diffuse at a faster rate than heavier gases under the same conditions.
Some physical effect is reduced in proportion to the square of the distance from it's source. It applies to most forces or energies that radiate from a single point, like a light bulb. If you move twice as far from the light source, you will receive only a quarter as much light. And if you move three times as far from the bulb, you will receive only 1/9 as much. 1/4 is the inverse of 22 and 1/9 is the inverse of 32. If you are using the acoustics it is different, because the sound pressure is inversely proportional to the distance (1/r) from the source. That is the inverse distance law.

Newton's Law of Universal Gravitation states that every massive particle in the universe attracts every other massive particle with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
