What else can I help you with?
What are radios?
a device that converts radio waves to audio waves
Do radio and television waves affect global warming?
No. Radio/television waves do not affect the temperature, but usage of radios and televisions definitely does.
Is a radio and example of radiant energy?
Yes. Radios use radio waves which are radiant energy.
Do computers use radio waves?
Absolutely. Computing is highly integrated into radio frequency (RF) type communications. Examples of RF integration include Bluetooth, WiFi, and RF peripherals such as the mouse and keyboard.
Were there radios in 1851?
No. Radio waves were discovered around 1880. The first radio stations began about 1920..
What are uses for radio waves?
Regular household AM radios pick up stations on frequencies between 550 KHz to 1.7 MHz . . . wavelengths between 176 meters and 545 meters. Regular FM radios pick up stations on frequencies between 88 MHz and 108 MHz . . . wavelengths between 2.8 meters and 3.4 meters. 'Short wave' radios, taxi radios, police radios, CB radios, firetruck radios, aircraft radios, weather radios, satellite radios, toy walkie-talkie radios, cellphone radios, computer WiFi radios, cordless telephone radios, garage door opener radios, Bluetooth radios, 4G iPad radios, and microwave oven radio transmitters all have their own separate frequencies/wavelengths that they operate on, so that they don't all interfere with each other.
What do am radios convert sound into?
AM transmitters convert sound into amplitude modulated radio waves which am radios convert into electrical pulses which speakers convert into air waves that are converted into sound by our eardrum.
How are radio waves formed?
Radio waves are a type of electromagnetic radiation that are emitted by accelerating electric charges. When electrons within an antenna are oscillated or accelerated, they create electromagnetic waves at radio frequencies. These waves then propagate through space and can be received by devices like radios or antennas.
What are the waves called that radios use?
Radio waves. They are a form of electromagnetic waves with a much lower frequency than light, meaning a longer wavelength.
Why don't Crystal Radios need a power source?
Crystal Radios don't need a power source because, the crystal runs on the radio waves it receives.
What type of waves to cell phones use?
Radio, i.e. electromagnetic. They are simply two-way radios.
What are the other uses for Radio Waves?
Can be used to carry messages such as mobile phone texts and CV radios
