Acoustically, sound is created by:
Correct Answer
C. Pressure changes of varying frequency moving air in 'waves'
Explanation
Sound is created by pressure changes of varying frequency moving air in 'waves'. When an object vibrates, it causes the surrounding air particles to vibrate as well. These vibrations create pressure waves that travel through the air. The frequency of the vibrations determines the pitch of the sound, while the amplitude of the waves determines the volume. So, sound is essentially the result of these pressure changes in the air that propagate as waves.

What 2 features of the sound of the breaking sea waves change as Alan alters his distance from the sea?
Correct Answer
A. The volume decreases with further away from the sea, as does the amount of high frequency
Explanation
As Alan moves further away from the sea, the volume of the breaking sea waves decreases. This can be attributed to the fact that sound waves spread out and become less intense as they travel through the air. Additionally, the amount of high frequency content also decreases. High frequency sounds have shorter wavelengths and are more easily absorbed by the air and other obstacles, resulting in a decrease in their intensity as Alan moves away from the source of the waves.
