Carrier waves are used for communicating signals over long distances because:
- Acarrier waves can be generated very easily.
- Blow frequencies cannot be easily modulated by the carrier waves.
- Clow frequencies can be transmitted over long distances.
- Dcarrier waves generated at higher frequencies can be transmitted over long distances.
