WGVU-AM is a radio station that serves the Grand Rapids, Michigan area. The main broadcast frequency is 1480kHz. At a certain distance from the radio station transmitter, the magnitude of the magnetic field of the electromagnetic wave is 3.0x10^-11T. a. Calculate the wavelength
b. What is the angular velocity?
c. Find the wave number of the wave.
d. What is the amplitude of the electric field at this distance from the transmitter?

a

b

c

d

Explanation:

From the question we are told that  

       The frequency of the radio station is  

         The magnitude of the magnetic field is  

Generally the wavelength is mathematically represented as

Here c is the speed of light with value  

So

=>      

Generally the angular frequency is mathematically represented as

=>  

=>  

Generally the wave number is mathematically represented as        

=>      

=>      

=>      

Generally the amplitude of the electric field at this distance from the transmitter is mathematically represented as

=>      

=>
