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.
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.
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.
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
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.
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
the frequency range of an am wave is 20herz to 20kilo herz
because noise usually changes the amplitude not frequency.
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.
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 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.
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.
amplitude modulation is where we modulate our signal with a carrier signal amplitude changes but frequency remains constant in amplitude modulation

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.

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.
