Give a reason for the following:

It is necessary to use satellites for long-distance TV transmission. Why?

Advertisements

Solution

  1. It is necessary to use satellites for long-distance TV transmissions because television signals are of high frequencies and high energies. Thus, these signals are not reflected by the ionosphere.
  2. Hence, satellites are helpful in reflecting TV signals. Also, they help in long-distance TV transmissions.
