Question 1
For plane wave propagating in free space or two conductor transmission line, what must be the relationship between the phase velocity 
the group velocity 
and speed of light c?
the group velocity and speed of light c? Question 2
The electric field in an electromagnetic wave in vaccum) is described by
Where
speed of light is 
. What is the amplitude of the corresponding magnetic wave?
Where
speed of light is . What is the amplitude of the corresponding magnetic wave? Question 3
Assertion (A): TEM (Transverse Electro magnetic) waves cannot propagate with a hollow waveguide of any shape.
Reason(R): For a TEM wave to exit within the waveguide, lines of H field must be closed loops which requires an axial components of E which is not present in a TEM wave.
