Satellite communication uses the following electro magnetic waves

Key Points

• Microwaves are a type of electromagnetic wave with a wavelength ranging from 1 millimeter to 1 meter.
• They are widely used in satellite communication due to their ability to pass through the Earth's atmosphere with minimal interference.
• Microwaves carry signals over long distances and are suitable for high-frequency communication.
• Their short wavelength allows for the use of smaller antennas in satellite communication systems.

Additional Information

• Visible Light: Visible light is a part of the electromagnetic spectrum that is detectable by the human eye. It is not suitable for satellite communication due to high scattering in the Earth's atmosphere.
• X-Rays: X-rays are high-frequency electromagnetic waves primarily used in medical imaging and material analysis. They are not used for communication purposes because they are heavily absorbed by the Earth's atmosphere.
• Radio Waves: Radio waves are another type of electromagnetic wave used for communication, especially for long-distance and low-frequency signals. However, they are not as effective as microwaves for satellite communication due to their longer wavelength and lower frequency.
