Intensity of a wave is proportional to the square of its amlitude so it should decrese when the amplitude is decreased.

If the amplitude of a wave changes which also changes?

If the amplitude of a wave changes, the intensity of the wave also changes. The intensity of a wave is directly proportional to the square of its amplitude. So, as the amplitude increases, the intensity increases as well.


How does an increase in intensity change the amplitude?

An increase in intensity of a wave causes the amplitude to increase as well. This is because intensity is directly proportional to the square of the amplitude of the wave. So, as intensity increases, the amplitude of the wave also increases.


What is the relationship between wave amplitude and intensity?

Wave intensity is directly proportional to the square of the wave amplitude. This means that as the wave amplitude increases, the wave intensity increases by a larger factor. In other words, a small change in wave amplitude can result in a significant change in wave intensity.


How does amplitude affect light intensity?

Amplitude of light waves directly affects the intensity of light. As the amplitude increases, more energy is carried by the light wave, resulting in higher intensity. Conversely, a decrease in amplitude leads to lower light intensity.


What happens to the intensity of a wave if the amplitude decreases?

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 happens to the intensity of light as the amplitude of a light wave increases?

As the amplitude of a light wave increases, the intensity of light also increases. This means that the light becomes brighter and more powerful.


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 increases as amplitude increases?

As amplitude increases, the energy of the wave increases proportionally. This means that the wave carries more energy per unit time. Additionally, the intensity of the wave, which is the power per unit area perpendicular to the direction of wave propagation, increases as amplitude increases.


The amplitude of a sound wave increases. What happens to the sound?

If the amplitude of a sound wave increases, the sound will become louder. This is because amplitude directly correlates with the intensity or volume of the sound.


What happens to the loudness if the amplitude increases?

If the amplitude of a sound wave increases, the loudness or volume of the sound also increases. This is because amplitude is directly related to the intensity of the sound wave, which our ears perceive as loudness.


When amplitude of the wave increase what else increases?

When the amplitude of a wave increases, the energy carried by the wave also increases. Additionally, the intensity of the wave, which measures the power carried by the wave per unit area, increases proportionally to the square of the amplitude.


What is the relationship between intensity and amplitude in the context of sound waves?

Intensity and amplitude are directly related in the context of sound waves. Amplitude refers to the height of a sound wave, while intensity is the amount of energy carried by the wave. As the amplitude of a sound wave increases, so does its intensity. This means that a louder sound with a higher amplitude will have a greater intensity compared to a softer sound with a lower amplitude.
