Which has a higher frequencies am radio waves or fm radio waves?
FM radio has the higher frequency which is why it sounds better. AM is a lower frequency but can travel further because the waves bounce off
How are AM and FM waves different?
In FM, which is frequency modulaton, the information is "put onto" the radio waves by varying the frequency of the wave. In AM, which is amplitude modulation, the information is "put onto" the radio waves by varying the amplitude of the wave.
What is the meaning of FM in FM Radio?
FM means frequency modulation AM means amplitude modulation
What do AM waves and FM waves have in common?
Both are radio waves, meaning that they are electromagnetic radiation (light) with a wavelength longer than a metre. AM waves have a frequency of 520,000 Hz to 1,620,000 Hz (wavelengths of 580 metres to 185 metres) while FM waves have a frequency of 87,500,000 Hz to 108,000,000 Hz (3.4 metres to 2.8 metres). The signal is encoded onto AM waves by varying the amplitude (intensity) and onto FM waves by varying the frequency.
What is the frequency of radio wave?
Fm radio waves travel at various frequencies between 87.5 MHz and 108.0 MHz
What keeps radio waves and such from soaring off of earth into space?
Actually, radio waves do go out into space. However, depending on frequency, they do tend to bounce off of the ionosphere, which is why lower frequency waves such as AM and longwave have greater (on Earth) range than higher frequency waves, such as FM or microwave.

What does fm and am stand for?
AM-Amplitude modulated FM-Frequency modulated Explanation: The frequency and amplitude refer to the width and height of wavelengths in the radio waves that are used to transmit the signal. FM is usually a better signal than AM because the frequency of the waves is less distorted than amplitude.
How are AM and FM waves different?
In FM, which is frequency modulaton, the information is "put onto" the radio waves by varying the frequency of the wave. In AM, which is amplitude modulation, the information is "put onto" the radio waves by varying the amplitude of the wave.
What is the meaning of FM in FM Radio?
FM means frequency modulation AM means amplitude modulation
What are FM waves?
FM radio uses frequency modulation to broadcast sound over radio. FM radio waves are usually transmitted between 87.5 to 108.0 megahertz.

What is the frequency of radio wave?
Fm radio waves travel at various frequencies between 87.5 MHz and 108.0 MHz
What does FM stand for in radio frequency?
FM means Frequency Modulated.FM stands for modulation on frequency or frequency modulation.
FM signals travel as what changes?
FM signals travel as changes in the frequency of the wave.ANSWER: DEFINITELY not frequency remains the same.The duty cycle changes.It definitely IS the the frequency which changes. It changes at the same rate as the frequency of the modulation.It can be demodulated with a frequency discriminator. If the frequency remained constant and its "duty cycle" changed, the discriminator wouldn't demodulate it.
What is the difference between am radios waves and FM radio waves?
AM means Amplitude(=height) modulation, so the frequency stays the same and the message is coded into variations of the strength of the signal. FM stands for Frequency modulation. Here the strength of the signal stays the same and the message is coded into changes in frequency instead.
What is the limitation of radio waves?
Radio is limited by its own design. AM & FM bands are frequency transmitted as radio waves. However since earth is round waves travels directly they do not bend. So as a rule the higher the frequency the more direct they are FM frequency is considered as line of sight transmission AM will have more range since it operates at lower frequency. At very low frequency it is possible to transmit around the earth by using the ionosphere curvature
