Sky wave propagation is not possible for waves of frequency gt 30 MHz because

Statement 1: Sky wave communication is not used to transmit TV signals Statement 2: The ionosphere does not reflect TV signals, it transmits tham.

Statement 1: Ground wave communication is effective only at low frequencies in the range 500 kHz to about 1500 kHz Statement 2: The decrease in the intensity of the signal due to absorption by the earth and its atmosphere is higher for higher frequencies.

Statement-1 : In under water communication, sound waves with low frequency are better than those with high frequency. Statement-2 : When sound pressure amplitude exceeds the atmospheric and hyrostatic pressure, it sets up eddy and turbulent motions in water.

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

Statement-1: Communication in UHF/VHF regions can be established by space wave or tropospheric wave. Statement-2 : The refractive index of the ionosphere becomes very high for frequencies higher than the critical frequency.

Statement 1: Long distance radio broadcasts use short wave bands. Statement 2: Short wavelength signals are reflected by the ionosphere.

The electromagnetic wave of frequency 2 MHz to 30 MHz are

The electromagnetic waves of frequency 2 MHz and 30 MHz are

Perhaps, the most commonly used mode of communication involves use of free space as a communication channel between transmitter and receiver. The various possible modes of using of free space have been described below Ground wave communication : This mode is used for low frequency as at high frequency, losses become large. This is useful for distance of the order of 1 km. Space wave communication: The signals are transmitted directly from transmitter to receiver. There is no limit to upper frequency, but its range is limited to few hundred kilometers. The range depends on the height of transmitting antenna Sky wave communication : The signals are sent towards sky They are reflected back towards earth by ionosphere. Its range can be above 500 km. But, very high frequencies (above 10 MHz) are not reflected back. Satellite communication: The signals that cannot be reflected back by ionosphere are reflected back by satellite. Moon is a passive satellite of earth. The cordless phone installed in a house uses
