Waves decrease in amplitude as they radiate because their energy is spread out over a larger area as they travel away from the source. This phenomenon is known as wave attenuation, and it occurs due to factors such as absorption, scattering, and dispersion in the medium through which the wave is traveling. As a result, the wave loses intensity and its amplitude decreases.
What else can I help you with?
How will decreasing the amplitude of the sound waves from a TV affect its intensity?
Decreasing the amplitude of the sound waves will decrease the intensity of the sound coming from the TV. Intensity is directly proportional to the square of the amplitude, so reducing the amplitude will result in a corresponding decrease in intensity. This means that the sound will be quieter.
How does constructive and destructive interference effect amplitude in waves?
Constructive interference occurs when waves align to increase amplitude, while destructive interference occurs when waves align to decrease amplitude. Constructive interference results in a larger combined amplitude, while destructive interference results in a smaller combined amplitude, or even complete cancellation.
What happen to the amplitude of wave that experience destructive interference?
In destructive interference, the amplitudes of the two interfering waves cancel each other out partially or completely, resulting in a decrease in the overall amplitude of the wave at certain points. This reduction is due to the waves being out of phase, leading to a net decrease in the amplitude in the region of interference.
Which wave property changes when two waves interfere in the same meduim?
The amplitude of the waves can change when two waves interfere in the same medium. Depending on the type of interference (constructive or destructive), the amplitude can increase or decrease at different points along the medium.
When does the amplitude of the wave become smaller?
The amplitude of a wave can become smaller when it encounters resistance or damping in its medium, causing energy loss and a decrease in the wave's intensity. Additionally, interference with other waves, absorption by the medium, or distance from the source can also cause the amplitude to decrease.

What is the relationship between a waves energy and its amplitude?
The energy of a wave is directly proportional to the square of its amplitude. This means that as the amplitude of a wave increases, its energy also increases exponentially. Conversely, decreasing the amplitude of a wave will result in a decrease in its energy.
What type of waves have amplitude?
Mechanical waves such as sound waves and ocean waves have amplitude. Amplitude refers to the maximum displacement of a wave from its rest position. It determines the intensity or loudness of the wave.
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.
When you turn down the volume what will happen to the sound waves' amplitude?
Intensity of sound is dealt as volume in case of radio sets. Intensity is directly proportional to the square of amplitude. So as volume is turned down, intensity is reduced and so the amplitude is decreased.
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 could happen if the amplitude of ocean waves and sound waves change?
If the amplitude of ocean waves increases, it can lead to more powerful waves that may cause coastal erosion, flooding, and damage to marine infrastructure. In contrast, a decrease in amplitude could result in calmer seas, affecting marine navigation and ecosystems. For sound waves, higher amplitude means louder sounds, which can impact marine life communication and behavior, while lower amplitude might reduce sound clarity, affecting activities like sonar operation and underwater communication. Overall, changes in amplitude can significantly influence both marine environments and human interactions with them.
Do sound waves radiate?
yes
