Question

1. How is sound produced? 2. What are compressions and rarefactions?




answer asap​

Answer 1

Sound is a type of energy made by vibrations. When an object vibrates, it causes movement in surrounding air molecules. These molecules bump into the molecules close to them, causing them to vibrate as well. ... This “chain reaction” movement, called sound waves, keeps going until the molecules run out of energy.

Answer 2

Answer:

1.Sound is a type of energy made by vibrations. When an object vibrates, it causes movement in surrounding air molecules. These molecules bump into the molecules close to them, causing them to vibrate as well. This makes them bump into more nearby air molecules.

compressions are regions of high pressure due to particles being close together. rarefactions are regions of low pressure due to particles being spread further apart.
