DevinSound travels away from the source in waves, propagating through a medium such as air, water, or a solid material by causing particles to vibrate. As the particles vibrate, they transfer energy to neighboring particles, thus transmitting the sound wave outward. The sound wave will continue to travel until it loses energy and eventually dissipates.

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.
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.
A Sound from a source is refracted away from the surface of the earth what does it mean?
When a sound wave travels through different layers of the atmosphere with varying temperatures, it can result in the sound being refracted away from the surface of the Earth. This happens because the speed of sound changes with temperature, causing the sound wave to bend away from the normal propagation path.
How is the intensity of a sound related to the distance between the source and the receiver?
The intensity of a sound decreases as the distance between the source and the receiver increases. This is due to the spreading out of sound energy over a larger area as it travels further away, resulting in a decrease in the concentration of energy at the receiver.
What do you call the occurrence of a sound getting louder as it approaches and quieter as it travels away?
This phenomenon is known as the Doppler effect, where the pitch of a sound appears to change based on the relative motion between the source of the sound and the listener.
