    Long range radio transmission is possible when the radio waves are reflected from the ionosphere. For this to happen the frequency of the radio waves must be in the range:

    What is the range of frequencies of audio waves, infrasonics and ultrasonics ?

    A sound wave travels at a speed of 340 m/s. It its wavelength is 2 cm, what is the frequency of the wave ? Will it be in the audible range ?

    Propagation of radio waves The behaviour of electromagnetic waves of wavelength 10^(-3) m and higher (called radio waves) in their propagation through atmosphere is an important consideration in all modern forms of communication, radio, television, microwaves, etc. At low frequencies, radio waves radiated by an antenna near the earth travel directly following the surface of the earth. This is called wave-along-ground propagation. Radio waves of frequencies 2 MHz-20 MHz are reflected off the ionosphere. So, radio waves in this frequency range radiated from a certain point can be received at another point on the surface after being reflected by the ionosphere. This is known as skywave propagation. Television signals have frequencies in the 100-200 MHz range and penetrate ionosphere (no reflection), therefore, their propagation is not possible through sky waves. The reception of such waves is possible only if the receiver antenna directly intercepts the signals. Thus, television broadcasts are made from tall antenna to get larger coverage. This is known as space wave propagation. Answer the following questions. What is the frequency range of television signals?

    Frequency ranges for micro waves are:
