Are radio waves a form of sound or light?
When you listen to the radio, you are hearing sound, which has no resemblance to light, radio waves, or x-rays. However, the sounds you hear are created in the radio receiver, using information that was carried to your location by means of radio waves.
What are radiowaves and how they are formed?
Radio waves Radio waves are electromagnetic waves occurring on the radio frequency portion of theelectromagnetic spectrum.Discovery and utilizationRadio waves were first predicted by mathematical work done in 1865 by James Clerk Maxwell. Maxwell noticed wavelike properties of light and similarities in electrical and magnetic observations. He then proposed equations, that described light waves and radio waves as waves of electromagnetism that travel in space. In 1887, Heinrich Hertzdemonstrated the reality of Maxwell's electromagnetic waves by experimentally generating radio waves in his laboratory. Many inventions followed, making practical the use of radio waves to transfer information through space. Nikola Tesla and Guglielmo Marconi are credited with inventing systems to allow radio waves to be used for communication.For more information go to:http:/en.wikipedia.org/wiki/Radio_waves
What humans use radio waves?
Radio waves are used to transmit signals from a radio station, and you can receive the signals with a radio, and hear them as sound such as speech or music. The long wavelength of radio waves makes them a suitable medium for transmitting over a large range. it is also use in agriculture...... it is used to diagnose different diseases
Radio signals are broadcast by what waves?
Radio waves are electromagnetic waves. Electromagnetic waves include waves such as X rays, ultraviolet light, visible light, infrared rays and so on, but you probably imagine radio waves to be quite different from these waves. Of the various kinds of electromagnetic waves, radio waves have a longer wave length than infrared rays, and are defined by the Radio Law as 'electromagnetic waves with a frequency of less than 3,000 GHz (3 THz)'Ultralow frequency radio wavesbelow 3kHzradio waves3kHz~3THz infrared rays3THz~380THz visible light380THz~790THz ultraviolet light790THz~105THz X rays105THz~107THz γ raysabove 107THzNames of radio waves Frequency Wave length Principal applications VLF(Very Low Frequency) 3kHz ~ 30kHz 100km ~ 10km LF(Low Frequency) 30kHz ~ 300kHz 10km ~ 1km Vessel / Airplane beacon MF(Medium Frequency) 300kHz ~ 3MHz 1km ~ 100m AM radio, Marine radio, Amateur radio HF(High Frequency) 3MHz ~ 30MHz 100m ~ 10m Shortwave broadcasting, Marine / Air radio, Amateur radio VHF(Very High Frequency) 30MHz ~ 300MHz 10m ~ 1m TV, FM, Fire radio, Police radio, Disaster PA radio network UHF(Ultra High Frequency) 300MHz ~ 3GHz 1m ~ 10cm Low power radio, Mobile-phone, Taxi radio, Amateur radio, TV, Wireless LAN SHF(Super High Frequency) 3GHz ~ 30GHz 10cm ~ 1cm Satellite broadcasting, Radar EHF(Extremely High Frequency) 30GHz ~ 300GHz 1cm ~ 1mm Satellite broadcasting, Radio astronomy, Radar submillimeter waves 300GHz ~ 3THz 1mm ~ 0.1mm
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.
What is the range of frequencies of radio waves?
the frequency range of radio waves is ranging from 3kHz-300GHz
How do you increase the intensity of sound waves from a radio?
Increase the volume.
What is the frequency range of radio waves that can penetrate human body?
The frequency range that the radio waves can penetrate the human body is between 1Hz and 10 KHz. This frequency of the radio waves is however not dangerous.
What reflects radio waves at night?
Ionosphere
If you turn up your radio what does it increase?
sound waves
Do visible light waves have higher frequencies than radio waves?
Yes, visible light waves have higher frequencies than radio waves. Visible light waves fall within the range of frequencies on the electromagnetic spectrum that is higher than radio waves.
What is The entire range of electromagnetic waves such as light radio waves microwaves and x rays?
The entire range of electromagnetic waves includes gamma rays, X-rays, ultraviolet light, visible light, infrared radiation, microwaves, and radio waves. These waves vary in frequency and energy, with gamma rays having the highest energy and radio waves having the lowest.
Which property of sound waves changed when you increase the volume on a car radio?
The amplitude of the sound waves increases when you increase the volume on a car radio. Amplitude is directly related to the loudness or volume of the sound.
How far do radio waves travel and what factors affect their range?
Radio waves can travel long distances, sometimes thousands of miles, depending on factors like frequency, power, and obstacles in the environment. The range of radio waves can be affected by interference, atmospheric conditions, and the curvature of the Earth.
What type of waves does a cellphone use?
Cellphones use radio waves for transmission and reception of signals. These waves are a type of electromagnetic radiation that falls within the radio frequency range.
What is the frequency of radio wave?
Fm radio waves travel at various frequencies between 87.5 MHz and 108.0 MHz
What range of wavelengths is outgoing terrestrial radiation?
Radio waves, mostly.
