The speed of wave of time period `T` and propagation constant `K` is

The dimensions of the propagation constant of the wave is

SI unit of angular wave number or propagation constant is

In the equation of a simple harmonic progressive wave of wavelength 'lamda' , the propagation constant is given by

As a wave propagates

The speed of a periodic wave is the product of its

A: The speed of light in vaccum doesn't depend on nature of the source, direction of propagation nature of the source, direction of propagation, motion of the source , or observer wavelength and intensity of the wave. R: The speed of light in vaccum is a universal constant independent of all the factors listed and anything else.

As a wave propagates,

A wave of angular frequency 30 rad//sec propagates so that a certain phase of oscillationn moves along x-axis, y-axis , z-axis with speeds 1m//s , 2m//s and 2m//s respectively. The propagation constant K is

If V is the velocity of the wave and omega is the angular velocity then the propagation constant (K) of the wave is given by
