The movement of particles in a medium, such as air or water, affects the frequency and amplitude of a wave passing through that medium. As particles move more vigorously, the amplitude of the wave increases. Similarly, as particles move faster (higher frequency), the frequency of the wave passing through the medium increases.
What else can I help you with?
What changes in the wave when you increase the amplitude?
Increasing the amplitude of a wave increases the maximum displacement of the wave particles from their equilibrium position. This results in a higher energy and intensity of the wave. It does not affect the frequency or wavelength of the wave.
Is the amplitude of a wave changes what changes?
If the amplitude of a wave changes, the wave's intensity, energy, and loudness (in the case of sound waves) would also change. The wavelength and frequency of the wave remain unaffected by changes in amplitude.
What is the formulae for finding amplitude of sound?
Amplitude= velocity/frequency Sound velocity is known for many materials, e.g., air The frequency changes, according with: high voice - high frequency (low amplitude) and vice versa
How are the frequency and the amplitude of a wave mathematically related?
The frequency and amplitude of a wave are independent of each other in traditional wave equations. Frequency refers to the number of oscillations per unit time, while amplitude is the maximum displacement of a point on the wave from its equilibrium position. However, in some specialized cases, changes in frequency can affect the amplitude through phenomena such as resonance.
What affect if any does frequency have on the amplitude of a wave?
The sound pressure amplitude tells about how loud the tone will be and the frequency (cycles per second) of the oscillation tells how high the sound of the tone will be. The amplitude gives the loudness of the tone: http://en.wikipedia.org/wiki/Loudness The frequency gives the pitch of the tone: http://en.wikipedia.org/wiki/Pitch_%28music%29
What is the modulating frequency of amplitude modulation?
the frequency range of an am wave is 20herz to 20kilo herz
Why is amplitude modulation susceptible to noise but not frequency modulation?
because noise usually changes the amplitude not frequency.
What is the usage of frequency modulation?
It is a device or electronic circuit that changes the frequency of an oscillator according to the amplitude of modulating signal. For instance, if the modulation is linear, the modulator changes the frequency proportional to the amplitude of the modulating voltage.
What changes in the wave when you increase the amplitude?
Increasing the amplitude of a wave increases the maximum displacement of the wave particles from their equilibrium position. This results in a higher energy and intensity of the wave. It does not affect the frequency or wavelength of the wave.
AM radio and FM radio?
AM stands for amplitude modulation, while FM stands for frequency modulation. In AM, the amplitude (the height or depth of the crests or troughs) changes, while in FM, the frequency changes.
Is the amplitude of a wave changes what changes?
If the amplitude of a wave changes, the wave's intensity, energy, and loudness (in the case of sound waves) would also change. The wavelength and frequency of the wave remain unaffected by changes in amplitude.
Multiple choice question answer of AM modulation?
amplitude modulation is where we modulate our signal with a carrier signal amplitude changes but frequency remains constant in amplitude modulation

Amplitude= velocity/frequency Sound velocity is known for many materials, e.g., air The frequency changes, according with: high voice - high frequency (low amplitude) and vice versa

What is the difference between FM and AM 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 affect if any does frequency have on the amplitude of a wave?

Wavelength frequency amplitude and what are the four characteristics of waves that can change?
The four characteristics of waves that can change are wavelength, frequency, amplitude, and speed. These changes can be influenced by the medium through which the wave is traveling, such as air, water, or a solid material.
