Draw a schematic diagram showing the (i) ground wave (ii) sky wave and (iii) space wave propagation modes for em waves.
Write the frequency range for each of the following :
(i) Standard AM broadcast (ii) television (iii) Satellite communication

Explanation

(i) Ground wave:

Standard AM broadcast `to 500 KHz" to " 1500 KHz`.
(ii) Sky wave : Television `to 1710 kHz " to " 40 MHz`.

(iii) Space wave : Setellite communication `to` upto 1710 kHz.
Direction of propagation `to`
