Homework SourseThe voltage of an electromagnetic wave traveling on a transm
The voltage of an electromagnetic wave traveling on a transmission line is given by v(z,t)=5e^-alpha*z(4pi*10^9t-20pi*z) volt, where z is the distance in meters from the generator. Find the frequency
A) 2.5Ghz
B) 5 Ghz
C) 2Ghz
D) 20 ghz

Solution
(z,t) = 5e-az sin(4 ×109 t 20z)
= 4 × 109 rad/s
, f = /2 = 2 × 109 Hz = 2 GHz;
so answer is option C .
