There's no difference between a frequency-modulated wave and an amplitude-modulated
wave. Either kind can be generated and transmitted with any wavelength you want.
In the USA, however, AM broadcast stations are licensed to operate only in the band 550-1700 KHz,
and FM broadcast stations are licensed to operate only in the band 88-108 MHz. So for ordinary
programs that you listen to on an ordinary radio, the AM stations all have longer wavelengths
than the FM stations have.
What else can I help you with?
why are radio waves invisible?
When a wave's wavelength is larger than the size of an object, the wave flows around the object, and has no significant effect on the internals of that object. Because the wavelength of a radio wave is much larger than the light-sensitive protein in the retina of the human eye, a radio wave does not trigger the change in that protein that would cause a neural signal to be sent to the brain.
The wavelength of a radio wave received at 100 megahertz is?
Wavelength = speed/frequency = 300,000,000/100,000,000 = 3 meters
What is the longest wave length?
Radio waves are the electromagnetic waves with longest wavelength.
What is the minimum wavelength of a radio wave?
Extra-low frequency radio waves can have wavelengths as long as 3.5 miles or more. The shortest wavelength is around 1 mm.
What is the wavelength of the 60 thousands hz radio wave used by radio controlled clocks and wristwatches?
Wavelength = (speed) divided by (frequency) = (300,000,000) / (60,000) = 5,000 meters
What type of wave has longest wavelength?
In the electromagnetic spectrum, it is the radio wave that has the longest wavelength. Some radio waves are over 100 yards long.
What type of wave has the longest wavelength and the lowest frequency?
The type of wave that has the longest wavelength and lowest frequency is a radio wave. These waves are used for communication and broadcasting due to their ability to travel long distances.
What wave has the greater wavelength?
A radio wave has a greater wavelength compared to a visible light wave.
What type of wave is a microwave?
a microwave is an electromagnetic wave.================Answer #2:A microwave is a radio wave with a wavelengthless than 10 cm (frequency greater than 3 GHz).
What is a wave with the longest wavelength and lowest frequency?
The type of wave with the longest wavelength and lowest frequency is a radio wave. These waves have frequencies ranging from about 3 kHz to 300 GHz and are used for various forms of communication, including radio broadcasts and mobile phone signals.
What is different about each type of electromagnetic wave?
Each type of electromagnetic wave differs in terms of frequency, wavelength, and energy. For example, radio waves have low frequency and long wavelength, while gamma rays have high frequency and short wavelength. These differences determine the properties and behaviors of each type of electromagnetic wave.
What are the components of a radio wave?
Speed, wavelength and frequency.
Is a microwave?
A short-wavelength radio wave. An electromagnetic wave that is somewhere in between regular radio waves and infrared radiation.
Which wave has the longest wavelength in the electromagnetic spectrum?
Radio waves have the longest wavelength in the electromagnetic spectrum.
What type of electromagnetic wave is the largest?
The section we call 'radio'. Of course, there's no end to the electromagnetic spectrum, at least not on the low-frequency end, so there's really no such thing as "greatest" wavelength. As frequencies go down past radio and below, wavelength just keeps getting longer ... the bit of radiation from the 60 Hz utility power lines has a wavelength of almost 5,000 kilometers ( ! ! ). But we don't use anything down there in the form of radiation ... antennas would need to be gigantic in order to be the least bit efficient ... so there's no popular name for the radiated form. The 'generic' answer to the question is: The type with the lowest frequency.

How long is a radio wave's wavelength?
Anything in the range of something like 1 millimeter to 5,000 kilometers is called a radio wave.
