Intensity of a wave is proportional to the frequency squared and amplitude squared based on this formula;
I=1/2pw^2A^2V where p is the density of the medium, w is the angular frequency and A is the amplitude and V is the wave velocity.
So, everything else remaining constant, decreasing the amplitude will decrease a waves intensity. Example decreasing the the amplitude by a factor of 4 will decrease the wave intensity by a factor of 8.
What else can I help you with?
Does the intensity of a wave increases when its amplitude decrease?
Intensity of a wave is proportional to the square of its amlitude so it should decrese when the amplitude is decreased.
What happens to the amplitude of a wave when the wave is being absorbed?
When a wave is being absorbed, its amplitude decreases as energy is transferred to the absorbing medium. This results in a reduction of the wave's intensity and amplitude as it loses energy.
Is it true that sound intensity decreases when the amplitude decreases?
Yes, the sound intensity is directly proportional to the square of the amplitude of the sound wave. Therefore, when the amplitude decreases, the sound intensity also decreases.
What happens to the volume of a sound wave as its amplitude decrease?
As the amplitude of a sound wave decreases, the volume or loudness of the sound also decreases. This is because amplitude is directly related to the intensity of the sound wave, which in turn affects how loud the sound is perceived. So, a lower amplitude results in a quieter sound.
What happens to a light if the amplitude of the wave decreases?
If the amplitude of a light wave decreases, the intensity of the light will also decrease. This means that there will be fewer photons or less energy carried by the light wave. As a result, the brightness of the light will be reduced.

What happens to a wave when energy is absorbed?
When energy is absorbed by a wave, the wave's amplitude decreases and its intensity weakens. This can cause the wave to lose momentum and eventually dissipate.
What rises and falls in sound intensity?
The amplitude of a sound wave rises and falls to create variations in sound intensity. As the sound intensity increases, the amplitude of the sound wave increases, resulting in a louder sound. Conversely, as the sound intensity decreases, the amplitude of the sound wave decreases, resulting in a quieter sound.
What happens when you change the amplitude on a light wave?
Changing the amplitude of a light wave affects its brightness. A higher amplitude increases the intensity and makes the light appear brighter, while a lower amplitude decreases the intensity and makes the light appear dimmer. However, changing the amplitude does not affect the color or wavelength of the light wave.
What happens to intensity if the amplitude of sound is doubled?
If the amplitude of a sound wave is doubled, the intensity of the sound wave will increase by a factor of four. This is because intensity is proportional to the square of the amplitude of the wave.
Intensity decreases when?
Intensity decreases when the energy of the wave is spread out over a larger area or when the amplitude of the wave decreases. This can happen due to factors such as distance from the source, absorption by the medium, or the spreading out of the wave as it propagates.
When the amplitude decreases what happens to the frequency?
When the amplitude decreases, the frequency remains constant. Amplitude and frequency are independent of each other in a wave. The frequency determines the pitch of the sound or the color of light, while the amplitude determines the intensity or loudness of the sound or brightness of light.
What happens to the wave amplitude?
The wave amplitude measures the intensity or strength of a wave. It typically decreases as a wave travels further from its source due to factors like energy loss and dispersion. However, in some cases, waves can maintain their amplitude if energy is consistently added back into the system.
