They are used for carrying information. Mobile phones, satellites, radio and TV broadcasting, cb radio, radars, GPS, deep space research - these are just a few examples of radio waves' possible applications.
False. For some bands of radio waves the atmosphere is transparent. Radio waves can penetrate to the ground. That's why we have radio telescopes on the Earth.
Remote controls use both infrared and radio frequency technologies. Your typical TV remote uses infrared and your typical car remote uses RF.
Both are electromagnetic waves.
I do not believe that the Hubble is equipped for radio astronomy. Certainly it can "detect" radio waves; it is remote-controlled by radio. But most radio astronomy is done with earth-based dish antennas.
radio waves.
it doesn't, it uses microwaves
bluetooth is an open wireless protocol for exchanging data over short distances. it uses short length radio frequencies. bluetooth uses a radio technology called frequency-hoping spread spectrum.
1930
it uses radio waves
Yes. A good rule of thumb is that if the device has an antenna, it uses radio waves. An antenna would not be needed if it didn't use radio waves.
RADAR (RAdio Detection And Ranging)
Radio waves are used to help transmit signals between two devices.Some devices which use radio waves are:RadiosTelevisionsMobile (cell) phonesCordless telephonesNavigational devices (such as GPS and satellite tracking)RadarRadio-tuned clocks and watchesRadio telescopes
Wireless.
Radio and gamma waves are two types of electromagneticwaves.
One uses infrared light and the other uses radio waves. Hope this helps!
Radar uses radio waves.
By Internet waves, one would assume you mean WiFi. When talking about WiFi, it does not use electromagnetic waves but instead uses radio waves like your TV or radio does.
