A satellite phone can be used to place a call from virtually anywhere in the world. What type of wave does the satellite phone likely transmit to the satellite orbiting above Earth?
sound wave
visible light
gamma ray
radio wave
more than likely D
Gamma rays are most unlikely.
either radio or gamma
To determine the type of wave that a satellite phone likely transmits to the satellite orbiting above Earth, we need to understand how satellite communication works.
Satellite phones use a system of satellites in geostationary orbit or low Earth orbit to relay calls and data. In this system, the phone transmits signals to the satellite, which then relays those signals to the desired destination.
The most common type of wave used for satellite communication is a radio wave. Radio waves are a form of electromagnetic radiation with relatively low frequencies and long wavelengths. They can travel through space and the Earth's atmosphere, making them suitable for long-distance communication.
Sound waves, on the other hand, are mechanical waves that require a medium (such as air, water, or solids) to propagate. Since there is no medium in space, sound waves cannot travel from a satellite phone to a satellite.
Visible light and gamma rays are other forms of electromagnetic radiation, but they are not typically used for satellite communication due to their limited range and susceptibility to atmospheric interference.
In conclusion, the type of wave that a satellite phone likely transmits to the satellite orbiting above Earth is a radio wave.
