AM stands for Amplitude Modulation.
Whatever radio frequency you use, a single frequency would just produce silence at the receiver.
You need to superimpose sound frequencies onto the carrier wave.
Amplitude modulation does this by varying the Amplitude (strength, power) of the radio carrier wave in time with audio frequency.
AM is therefore the kind of 'coding' used and has nothing to do with frequency.
By convention, amplitude modulation is mostly used in the medium and long, radio waves. From 150 to 1600 Khz.
AM is also used for air band communications at 121Mhz, whereas FM is used at marine frequencies of 156Mhz.
What else can I help you with?
Can A standing wave can only occur at natural frequencies?
A standing wave can occur only at specific frequencies that are called natural frequencies.
What units are wave frequencies measured in?
Wave frequencies are typically measured in hertz (Hz), which represents the number of cycles per second.
A wave with which frequencies would have the shortest wavelength?
a wave with the highest speed
What are the frequencies and wavelength of each type of wave?
Each type of wave has a range of frequencies. Visit this site for a good explanation- http://en.wikipedia.org/wiki/Electromagnetic_spectrum
What is the term for the blending overlaping sound wave frequencies through interference?
Sound quality is the term for the bending of overlapping sound wave frequencies through interference.
What electromagnetic wave has the shortest frequencies?
stellar waves
How does the superposition of two waves with different frequencies and amplitudes affect the resulting wave pattern?
When two waves with different frequencies and amplitudes are superimposed, they combine to create a new wave pattern. The resulting wave will have a complex pattern that is a combination of the individual waves. The amplitudes and frequencies of the original waves will influence the shape and characteristics of the resulting wave pattern.
What type of wave is used for a laser?
A laser generates an electromagnetic wave operating at light frequencies.
Does waves with longer wave lengths have a higher frequency that waves with shorter wave lenghts?
No, waves with longer wavelengths have lower frequencies and waves with shorter wavelengths have higher frequencies. Frequency is inversely proportional to wavelength in a wave.
What determines wavelength?
The wavelength of a wave is determined by the speed of the wave and its frequency. It can also be influenced by the medium through which the wave is traveling. In general, longer wavelengths are associated with lower frequencies and shorter wavelengths are associated with higher frequencies.
Is determined by the medium wave?
The determination of the medium wave frequency range is between AM and FM radio frequencies. Medium waves have lower frequencies than FM but higher frequencies than long waves. They are commonly used for AM radio broadcasting.
How is pitch related to wave speed?
Pitch is related to wave speed through the frequency of the wave. Higher frequencies correspond to higher pitches, while lower frequencies correspond to lower pitches. In general, waves with higher frequencies travel faster than waves with lower frequencies.
