Radio station WCCO in Minneapolis broadcasts at a frequency of 830 kHz. At a point some distance from the transmitter, the magnetic-field amplitude of the electromagnetic wave from WCCO is 4.82×10-11 T. A) Calculate the wavelength. B) Calculate the wave number. C) Calculate the angular frequency. D) Calculate the electric-field amplitude.

A

B

C

D

Explanation:

From the question we are told that

   The frequency is

    The  magnetic field amplitude is  

Generally wavelength is mathematically represented as

where c is the speed of light with value  

     =>  

     =>  

Generally the wave number is mathematically represented as

=>    

=>    

Generally the angular frequency is mathematically represented as

=>  

=>  

The the electric-field amplitude is mathematically represented as

=>    

=>    

change tension

a.) travels faster in solids because the particles are closer together.
