The sound gets softer.

What happens to the energy of a sound wave as the source gets farther away?
As a sound wave travels away from the source, its energy spreads out over a larger area, leading to a decrease in the intensity of the sound. This reduction in energy leads to a decrease in the loudness of the sound as it travels farther away.
What happens to the amplitude of a sound wave when it hits a wall?
When a sound wave hits a wall, the amplitude of the wave decreases due to reflection. Some of the sound energy is absorbed by the wall, some is transmitted through it, and some is reflected back into the original space. This results in a decrease in the overall energy and amplitude of the sound wave.
As the speed and length of wave decrease what happens to the wave?
As the speed and length of a wave decreases, the frequency of the wave remains constant. This means that the wave will experience a decrease in wavelength, which is inversely proportional to the decrease in speed. The energy of the wave will also decrease.
What happens to a wave when you decrease the wave height?
it gets smaller and then there is no more energy to make it travel
Why does the loudness of a sound wave decrease as the wave travels away from it source?
The energy in the sound's vibration dies down, until it is no longer audible.
As the speed and length of a wave decrease what happens to the wave?
As the speed and length of a wave decrease, the frequency remains the same while the wavelength decreases. This means that the wave's energy decreases as well.
What happens when a waves energy is lost to a surface making the wave weaker?
When a wave's energy is lost to a surface, it is typically converted into other forms of energy such as heat or sound, which results in a decrease in the wave's intensity. This process is known as energy dissipation or absorption, and it leads to the attenuation and weakening of the wave as it travels through the medium.
Why does a sound wave decrease over time?
A sound wave decreases over time because of natural dissipation, which refers to the energy lost as the sound propagates through a medium like air. As the wave travels, some of its energy is converted into other forms (like heat) and is no longer available to keep the wave going, resulting in a decrease in amplitude and intensity over distance.
What happens to sound wave energy if it triggers hearing receptors in the cochlea?
When a sound wave triggers hearing receptors in the cochlea, the energy of the sound wave is converted into electrical signals that are sent to the brain for processing. This conversion allows us to perceive and interpret the sound.
Why does the loudness of a sound wave decrease as the wave travels away from its source?
The loudness of a sound wave decreases as it travels away from its source due to the spreading out of energy in all directions. This phenomenon is known as sound attenuation, where sound energy is dissipated through interactions with the surrounding medium. Additionally, absorption, reflection, and scattering of sound waves by air molecules and obstacles in the environment contribute to the decrease in loudness.
What happens to the air particles as the sound wave travels through them?
As the sound wave travels through the air, the air particles vibrate back and forth in the direction of the wave, transferring the sound energy.
What happens to the wave when you decrease the wavelength or increase the wavelength?
When you decrease the wavelength of a wave, its frequency and energy increase. This is known as blue shift and is common in light waves. Conversely, when you increase the wavelength of a wave, its frequency and energy decrease. This is known as red shift and is also observed in light waves.
