Question about Office Equipment & Supplies
For a plane wave in a homogeneous medium, the phase velocity of the wave is related to the frequency and the wavelength by the relation
velocity = wave_length*frequency
In this case
velocity (in m/s)=(4*10^-3 m )*(3*10^9 s^-1)=12*10^(9-3)=12*10^6
Thus velocity=1.2*10^7 m/s
