Direction: Question consists of two statements, one labelled as the 'Assertion (A)' and the other as 'Reason (R)'. Examine these two statements carefully and select the answer to this question using the codes given below:Assertion (A): TEM (Transfer Electro-Magnetic) waves cannot propagate within a hollow waveguide of any shape.Reason (R): For a TEM wave to exist within the waveguide, lines of the H field must be closed loops that require an axial component of E which is not present in a TEM wave.
