Assertion (A): As the length of the resonant antenna is increased, the number of lobes increases and the direction of the major lobes is closer and closer to the direction of the diode.

Reason (R): As the length increases, the current distribution along the wire becomes more and more uniform.

The electric field of uniform plane wave is given by E = 20 sin (2 p x 10^{8}t- pz) _{x} + 20 cos (2 p x 10^{8}t - pz) _{y}. The wave propagates in direction of
