Q. Assertion: It is not necessary for a transmitting antenna to be at the same height as that of receiving antenna for line-of sight communication.
Reason: If the signal is to be received beyond the horizon then the receiving antenna must be high enough to intercept the line-of sight waves.

Q. In communications system, the process of superimposing a low frequency signal on a high frequency wave is known as

Q. Assertion :Low frequency waves are transmitted via ground waves. Reason: When a wave has high wavelength, it undergoes more diffraction.

Q. A wave has a low speed but a high frequency. What can you infer about its wavelength?

Q. Assertion :The Earth does not receive an equal amount of solar energy at all latitudes. Reason: As one goes from low altitude to high altitude temperature decreases.
