inverse square law
(redirected from Inverse-square law)

inverse square law,
a law stating that the amount of radiation reaching a surface is inversely proportional to the square of the distance between the source and the surface. For example, a person standing 1 m from a patient being treated with radium is exposed to four times more radiation than a person standing 2 m from the patient.
law [law]
a uniform or constant fact or principle. For specific named laws, see under the name.
law of independent assortment the members of gene pairs segregate independently during meiosis; see also mendel's laws.
inverse square law the intensity of radiation is inversely proportional to the square of the distance from the source of radiation.
law of segregation in each generation the ratio of (a) pure dominants, (b) dominants giving descendants in the proportion of three dominants to one recessive, and (c) pure recessives is 1:2:1. This ratio follows from the fact that the two alleles of a gene cannot be a part of a single gamete, but must segregate to different gametes. See also mendel's laws.
inverse square law
for a given exposure the amount of radiation falling on a given area of radiographic film varies inversely as the square of the distance of that area from the source of irradiation in the focal spot.

For example, the observed behavior of the Earth revolving around the sun can be perfectly explained if the sun has a net positive charge and the planets have a net negative charge, since opposite charges attract and the force is an inverse-square law, exactly like the increasingly discredited theory of gravity.

I will also describe two equivalence experiments and a test of the inverse-square law of gravitation.

We know that if we go slowly it takes longer to get there; we know that when we fall down, the farther we fall the more it hurts; we know that the faster the motion of something that hits us, and the bigger it is, the more it hurts; we know that the farther we are from our Mommy, the fainter are her cries, though we never heard of the inverse-square law or anything much else in the language.
