Electromagnetic waves, such as radio waves and light waves, travel in a vacuum at 300,000,000 meters per second so the wavelength of a radio wave at any particular frequency can be calculated by using the formula:
[Wavelength in meters (m)] =
300,000,000 / [Radio frequency in cycles per second (Hz)]
AM (Medium and long wave) broadcasts:
Frequencies: 300 to 3,000 kilohertz (KHz)
Wavelengths in air: 1,000 meters to 100 meters
FM (UHF radio and television broadcasts):
Frequencies: 300 to 3,000 megahertz (MHz)
Wavelengths in air: 100 centimeters to 10 centimeters

∙ 7y agoThe wavelength of a radio wave is 300,000,000 divided by the frequency of the radio wave, in meters.
Some typical wavelengths
Middle of the AM radio band (1000 KHz, 1 MHz): wavelength is 300 meters
Radio Moscow, shortwave broadcast: wavelength is 43 meters
Channel 2 TV: wavelength is 6 meters
Middle of the FM radio band: wavelength is 3.1 meters
Cellular telephone: 35 centimeters
GPS satellite to your dashboard: 20 centimeters
Cooking power in your microwave oven: 12 centimeters
Weather radar: 7.5 centimeters
TV signal from a satellite to your home dish: 2.3 centimeters

∙ 12y agoWe generate and detect waves for purposes of communication, cooking, and scientific investigation,
in the frequency range of roughly 30 KHz to 300 GHz. That range of frequencies corresponds to
wavelengths of 1 millimeter to 10 kilometers.

How do AM radio and television wavelengths compare with X rays?
All wavelengths used for communication are longer than all infrared, visible, ultraviolet, and X-ray wavelengths.
What do you know about radio waves?
it is the longest wavelengths..
Which waves have shorter wavelengths radio waves or xrays?
X-rays have shorter wavelengths than radio, heat, infra-red, visible light, and ultra-violet.
Radio waves with wavelengths between 10cm and 1mm are called what?
No. Your cellphone, many TV stations, and the GPS satellites transmit wavelengths shorter than 1 meter. X-rays have wavelengths between 0.00000000001 and 0.00000001 meter. (1/100th of a nanometer to 10 nanometers)
Which electromagnetic waves have the shortest wavelengths and highest frequencies?
Those are called gamma rays, or gamma radiation.
What electromagnetic waves have the longest wavelengths?
Radiowaves have the longest wavelength of electromagnetic waves.
Do you measure photons energy with wavelengths?
you see how close the wavelengths are-- the closer, the more powerful it is. Here are the wavelengths- from least powerful to most powerful: Radiowaves, Microwaves, Infared Waves, Visable Light, Ultraviolet, X-rays, and Gamma rays.
What can you use radiowaves for?
Radiowaves can be used for communication. Radio stations use radiowaves to broadcast their content to radios.
Why can't you see infrared light or radiowaves with your naked eyes?
Answer Your brain can't see heat, ultraviolet light, radiowaves, X-Rays, etc. with your naked eyes, because these different kinds of light's wavelengths are either too long or too short for your naked eyes to see. So that is why you can't see infrared
When was Radiowaves created?
Radiowaves was created on 1997-09-16.
How does the wavelength of a wave change when the frequency changes?
Usually with electromagnetic waves, the frequency and energy is opposite to the wavelength. An EM wave such as radiowaves have huge wavelengths, slow frequencies and small amounts of energy. An EM wave such as X-rays have tiny wavelengths, fast frequencies and large amounts of energy.
How are radiowaves detected?
By a satellite dish
What is before microwaves in electromagnetic spectrum?
radiowaves
Do laptops use microwaves or radiowaves?
PENIS
What energy is it when a radio plays?
radiowaves doiih
What led to the creation of the television?
radios and radiowaves
Is sunlight and radiowaves a good example of compression waves?
Sunlight and radiowaves are examples of electromagnetic waves, which are transverse mechanical waves. Sound waves are compression waves.
