Why microwaves can be used for satellite TV communications but not terrestrail TV?
Microwaves can be used for satellite TV communications because they can travel long distances with minimal attenuation and penetrate the Earth's atmosphere effectively, allowing signals to be transmitted from satellites in orbit to ground receivers. In contrast, terrestrial TV often uses lower frequency signals that are better suited for covering shorter distances and penetrating buildings. Additionally, terrestrial TV relies on a network of ground-based transmitters that are optimized for local broadcast rather than long-range transmission like satellites. Thus, the characteristics of microwaves make them ideal for satellite communication, while terrestrial systems utilize different frequencies.

What are 2 uses for microwaves?
Microwaves are commonly used for cooking food quickly and efficiently. Another use is in communication systems, such as cell phone networks and satellite communications.
What are the properties of microwaves that allow them to be used for satellite communications?
Microwaves have properties such as high frequency and short wavelength, which allow them to carry large amounts of data efficiently. Their ability to penetrate the atmosphere with minimal attenuation makes them ideal for long-distance communication, as they are less affected by weather conditions compared to lower-frequency signals. Additionally, microwaves can be easily focused into narrow beams, enabling precise targeting of satellite signals to specific areas on Earth. These characteristics make microwaves highly suitable for satellite communications.
What type of electromagnetic waves are used in satellite TV?
Satellite TV uses microwaves, which are a type of electromagnetic wave. These microwaves travel between the satellite in space and a receiver on the ground to transmit television signals.
Which type of electromagnet radiation is used in satellite communication networks?
Microwaves. These poke through the ionosphere to reach the satellite
What two uses for microwaves?
Microwaves are commonly used for cooking food quickly and efficiently. They are also used in communication technology, such as in radar systems and satellite transmissions.
How are microwaves are used in communications?
the waves are sent to satelites orbiting the earth when you use a mobile
Can micro waves travel through a vacuum?
Yes, microwaves can travel through a vacuum because they are a form of electromagnetic radiation, which can propagate through empty space. This is why microwave communication works in space and is used in satellite communications.
What do they use microwaves for?
Microwaves are commonly used for cooking and heating food quickly. They work by exciting water molecules in food, causing friction and generating heat. Microwaves are also used in communication technology, such as for satellite communication and radar systems.
What is the difference between microwaves in ovens and microwaves used in phones and satellite tv?
nothing really, they are just put in different devices to make them perform different jobs.
What is Microwave Technology?
Terrestrial microwave technologies share with satellite microwave technologies many of the scientific and technical improvements used to accomplish microwave transmissions. They are different in that satellite microwave technolgies seek to neutralize the effects of the atmosphere in the microwave transmissions. On the other hand, terrestrial micowave technologies seek the aid of atmospheric effects on microwaves to extend the range limitations imposed by the Earth's curvature. Examples of these terrestrial technologies include those used to exploit troposcattering and meteor-burst in microwave communications--not used at all in satellites. Professor Martinez
How are microwaves utilized in communication systems?
Microwaves are used in communication systems to transmit signals over long distances. They are used in technologies like satellite communication, radar systems, and cell phone networks. Microwaves have a high frequency and can carry a large amount of data quickly and efficiently.
Why are micro waves used for communication?
Microwaves are used for communication because they have a shorter wavelength than radio waves, allowing for higher frequencies and greater data transfer rates. They can also be easily focused into narrow beams for point-to-point communication, making them ideal for long-distance transmissions such as satellite communications. Additionally, microwaves are less susceptible to interference from weather conditions compared to lower frequency radio waves.
