The waves relevant to telecommunication are
Open in App
Solution
The correct option is D Microwave
Explanation:
- Microwave frequency is high enough to convey information, therefore, microwaves are utilized in telecommunication.
- Any impediment in their path does not absorb or scatter the microwaves.
Explanation for incorrect options:
Other rays cannot be used in communication for the following reasons:
- Visible light is reflected by the atmosphere.
- Infrared rays are influenced by hard objects such as walls, fog, and so on.
- UV rays are absorbed by the ozone layer. UV radiation can potentially be damaging to living things when employed in antenna-to-antenna communication.
Hence, the correct option is (D).
