Energy is lost as it travels - thus the wave length grows longer.
This is usually called 'redshift' as the wave radiated from the source shifts towards the less energetic red end of the electromagnetic spectrum (http://en.wikipedia.org/wiki/Electromagnetic_spectrum).
Wikipedia has more information on redshift - http://en.wikipedia.org/wiki/Redshift.

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 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.
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 frequency of a wave when the energy is increased?
When the energy of a wave is increased, the frequency remains the same. Frequency is determined by the source of the wave and does not change with energy.
What happens to a wave when the energy is absorbed and how does this affect its behavior?
When a wave's energy is absorbed, the wave's amplitude decreases and it may eventually disappear. This affects the wave's behavior by reducing its intensity and causing it to lose momentum as it travels through a medium.

What happens when a large wave travels through a small opening?
The wave diffracts and behaves like the opening is a point source.
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.
How do vibrations produce sound?
A sound wave is a transfer of energy as it travels away from a vibrating source.
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 when a source of energy causes medium to vibrate?
A Wave Forms .
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.
What is the Difference between wave and tsunami?
A tsunami wave is a wave of energy that travels through water, while a seismic wave is a wave of energy that travels through earth.
What is the difference between tsunami - seismic wave?
A tsunami wave is a wave of energy that travels through water, while a seismic wave is a wave of energy that travels through earth.
What happens to the frequency of a wave when the energy is increased?
When the energy of a wave is increased, the frequency remains the same. Frequency is determined by the source of the wave and does not change with energy.

When a wave's energy is absorbed, the wave's amplitude decreases and it may eventually disappear. This affects the wave's behavior by reducing its intensity and causing it to lose momentum as it travels through a medium.
What travels on a mechanical wave?
Energy travels on a mechanical wave. This energy causes disturbances in the medium through which the wave is traveling, such as air or water. The wave itself is the movement of this energy from one place to another.
