The sound waves after being converted into electrical waves are not transmitted as such because

Options

  1. Athey travel with the speed of sound
  2. Bthe frequency is not constant
  3. Cthey are heavily absorbed by the atmosphere
  4. Dthe height of antenna has to be increased several times

Correct answer

C. they are heavily absorbed by the atmosphere

Step-by-step solution

The electric waves do not have the capacity to travel through the atmosphere. They get immediately grounded and they become neutral as fast as possible. This makes electrical waves incapable to travel through the atmosphere.
