A sinusoidal wave with a frequency of 21 GHz is traveling at

A sinusoidal wave with a frequency of 2.1 GHz is traveling at the speed of light. Give the phase constant, the radian frequency, the period (recall that period is the reciprocal of frequency), and the wavelength. Don’t forget your units with your answers

Solution

Ans) Given F=2.1 GHz and Velocity of light Vp=3*10⁸ m/sec

Radian Frequency w=2*pi*F=13.195 G rad/sec

Phase Constant =w/Vp=13.195 G/3*10⁸

=43.98 rad/m

Period=1/F=1/2.1 G=0.476 nano- sec

Wave length= (2*pi)/ =(2*pi)/43.98=0.143 meters
