| Q. |
Circular polarization involves critical alignment between transmitting and receiving antenna. |
| A. | true |
| B. | false |
| Answer» B. false | |
| Explanation: in circular polarization at each point the electric field of the electromagnetic wave has a constant magnitude but its direction changes as it rotates with time at a steady rate, in a plane perpendicular to the direction of propagation of the wave. it is used to reduce depolarization effect on received waves. it does not involve alignment between transmitting and receiving antenna. | |
