Q106 / 160 · JIPMER 2012 · Physics

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

  • A
    they travel with the speed of sound
  • B
    the frequency is not constant
  • Correct answer
    C
    they are heavily absorbed by the atmosphere
  • D
    the height of antenna has to be increased several times

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.

Hence, the correct answer is option: 'C'.
