True or False? The wavenumber is directly proportional to the wavelength of an electromagnetic wave.

True or False? The average magnitude of the Poynting Vector is also known as intensity.

Suppose I produce radio waves with an antenna that have a peak electric field amplitude E and peak magnetic field amplitude B. If I were to double the amplitude of the electric field (i.e. double E) what is the new value for B?

Explanation / Answer

1) True

2) 1/(2*pi*sqrt(2*2))=1/(4*pi); now twice as much==>1/(2*pi*sqrt(4*4))=1/(8*pi)

answer 2) omega/2

3) False. It was to Ampere's law

4) False. Inversely proportional

5) True

6) 3) 2B
