Consider the following statements:1. Additional cavities serve to velocity-modulate the electron beam and produce an increase in the energy available at the output.2. The addition of intermediate cavities between the input and output cavities of the basic klystron greatly improves the amplification, power output, and efficiency of the klystron.Which of the above statements is/are correct?

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.
