How are microwaves used in communications?

Microwaves play a significant role in modern communications, particularly in satellite communications and mobile phone signals. This is due to their ability to penetrate the atmosphere effectively and travel long distances with relatively low energy loss. In satellite communications, microwaves are used to transmit signals to and from satellites orbiting the Earth, allowing for television broadcasts, internet connectivity, and global phone communication.

Microwaves are particularly advantageous in communication technology because they can carry large amounts of data at high frequencies, making them suitable for transmitting signals over large distances without the need for physical cables. This capability is essential for maintaining connections between ground stations and satellites and for facilitating mobile communication networks that connect numerous devices across vast geographical areas.

Other options, while they mention different uses of various forms of energy, do not pertain to the specific application of microwaves in the realm of communications.
