What does the inverse square law of light describe?

The fact that light from a point source obeys the inverse square law is used to measuring astronomical distances.If you have a source of known intrinsic brightness, then it can be used to measure its distance from the Earth.


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.


If the law of gravity instead of become inverse square law than?

If the law of gravity were not an inverse square law, the force of gravity between two objects would not decrease with the square of the distance between them. This means that the strength of gravity would not follow the same predictable pattern, leading to different gravitational interactions and behaviors in the universe.


Does gravitational pull lessen as you travel away from planets?

Yes, it obeys the inverse square law.


What does the inverse square law state?

any physical law stating that some physical quantity or strength is inversely proportional to the square of the distance from the source of that physical quantity.


What is the inverse square law for electric force?

The inverse square law for electric force states that the force between two point charges is inversely proportional to the square of the distance between them. Mathematically, it is given by F = k(Q1*Q2)/(r^2), where F is the force, Q1 and Q2 are the magnitudes of the charges, r is the distance between them, and k is the Coulomb constant.
