Explanation:Because mobile communication is a space communication and in space communication basically electromagnetic waves are used (as carrier waves as in case of radio communication) because of the modulation ( frequency, amplitude) operations which can be performed on EM waves. Thus when our friend receives the call, he also receives EM waves which is the carrier of our audio signals.

Electromagnetic Waves in Mobile Telephone Calls
When we make a mobile telephone call to a friend, the audio signals from our voice are transmitted as electromagnetic waves to the friend's mobile phone. This process involves several steps:
Audio to Electrical Signals
- When we speak into our mobile phone, our voice is converted into electrical signals by the microphone.
- These electrical signals are then sent to the mobile phone's transmitter.
Transmission as Electromagnetic Waves
- The transmitter in our mobile phone converts the electrical signals into electromagnetic waves.
- These electromagnetic waves travel through the air to reach the friend's mobile phone.
Reception by Friend's Mobile
- The friend's mobile phone receives the electromagnetic waves containing the audio signals.
- The receiver in the friend's phone then converts these electromagnetic waves back into electrical signals.
Playback of Audio
- The electrical signals are sent to the speaker in the friend's phone, where they are converted into acoustic waves.
- The friend hears the audio of our voice through these acoustic waves.
Therefore, when we make a mobile telephone call to a friend, the friend's mobile phone receives electromagnetic waves containing the audio signals of our voice. This allows for clear communication between callers over a distance.
