(1) These rays transmitted in the forward direction of medium with a finite speed.
(2) Energy and momentum are transmitted in the direction of propagation of waves without real transmission of matter.
(3) In progressive pulse, equal changes in density and pressure occurs at every points of medium.
The potential because of a continuous charge distribution is the sum of potentials of all the infinitesimal charge elements in which the distribution may be separated i.e.,
