A medium is known as denser if the velocity of ray in that phase is fewer than the speed of the wave in other phase.
In comparison to air velocity of sound is main in water, as water is rarer phase for sound waves w.r.t. air. But it is not right for light (EM-waves). For light rays water is denser medium w.r.t. air.
Regard as three resistors having three unique values of resistance. Presume the resistors are connected in parallel with each other. Additional suppose that the parallel combinatio
a column of water contains fine metal particles of radius 2*E(-8) m, which are in thermal equillibrium at 298 K. if there are 1000 particles per unit volume at a given height,how m
why can one ignore quantization of charge when dealing with macroscopic charges
The system below consist of identical massed (m1, and m2) that are connected by a string of negligible mass. Mass m1, is on a frictionless horizontal surface. The string runs over

As a longitudinal wave moves through a medium, the particles of the medium: a) vibrate in a path parallel to the path of the wave b) vibrate in a path perpendicular to the p
