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. Scroll down to related links and look at "Inverse Distance Law".

∙ 11y agoThe amount of illumination is inversely proportional to the distance from the light source.
In general, the inverse-square law states that the power intensity of an expanding wave is inversely proportional to the square of the distance from the source.
i.e. Intensity 1 / Distance2

What is the inverse square law of sound?
The inverse square law 1/r2 shows the distance performance for sound intensity, an energy quantity.But your ear drums are moved by the sound pressure vibrations using the inverse distance law 1/r for field quantities.Scroll down to related links and look at "Sound pressure pand the inverse distance law 1/r".Scroll down to related links and look at "Decreasing of Sound Intensity from a Point Source - Inverse square law of sound".
Who discovered inverse square law?
Charles Augustin de Coulomb is credited with the discovery of the inverse square law. It was used by Isaac Newton in his prismatic experiments.
What law states that the brightness of a star vaies inversely as the square of the distance from the stars?
The law is called The Inverse Square Law .
What is the inverse square law for electric force?
The law is that the attraction between electric charges is inversely proportional to the square of the distance. Note that the way the force varies with distance is identical to the gravitational force, which also follows an inverse-square law.
What is the significance of the inverse-square law?
Its the earth, wind and the fire
What is the relationship between distance and magnetic attrations?
The inverse square law.
Who invented the ''inverse square law''?
The concept of inverse square law was developed by Isaac Newton in the late 17th century. Newton formulated the law to describe the intensity of gravitational force, stating that the force between two objects is inversely proportional to the square of the distance between them. This concept of inverse square law is also applicable to other physical phenomena, such as light and sound.
Does the inverse square law apply to gravitational and electrical forces?
Yes. Both.
What does the inverse-square law tell you about the relationship between force and distance?
The inverse-square law applies to gravitational and electrical forces. An inverse-square law tells you:That the force is inversely proportional to the square of the distance.That means that if the distance is increased by a factor "n", the force is decreased by a factor "n2".For example, if you increase the distance by a factor of 10, the force will decrease by a factor of 102 = 10 x 10 = 100.
How is coulombs law similar to newtons law of gravity?
Both are 'Inverse square' forces, f=k/r2 .
Gravity decreases according to which law?
Gravity doesn't decrease. It follows the same simple mathematical formula at all distances.The mutual gravitational force of attraction between two mass objects decreases according tothe inverse square law.
Inverse operation of a square?
Square root is the inverse operation of a square.
