It is necessary to use satellites for long distance TV transmission because
  • a)
    Television signals are absorbed by ionosphere
  • b)
    Satellites transmit the signals all over the earth
  • c)
    Television signals are attenuated by ionosphere
  • d)
    Television signals are not properly reflected by the ionosphere. Therefore, reflection is effected by satellites.
Correct answer is option 'D'. Can you explain this answer?

  • TV signals being of high frequency are not reflected by the ionosphere. Therefore, to reflect these signals, satellites are needed. That is why, satellites are used for long distance TV transmission.
  • Most long-distance shortwave (high frequency) radio communication—between 3 and 30 MHz—is a result of skywave propagation.
  • This 3-30 MHz is a range of frequencies which are used in sky waves propagation so that the ionosphere is capable of reflecting it.
