Fluctuations in air pressure, often caused by vibration of an object, are known as:
A)sound waves.
B)ultraviolet radiation.
C)a nerve impulse.
D)light energy.

Question

Quizplus · Accepted Answer

Fluctuations in air pressure are the physical phenomenon that underlies the propagation of sound waves. Sound waves are produced when an object vibrates, causing fluctuations in air pressure that travel through the air as a wave. Therefore, option A is the correct answer. Option B is incorrect because ultraviolet radiation is a form of electromagnetic radiation and not related to fluctuations in air pressure. Option C is incorrect because nerve impulses are electrical signals that travel along the nerves in the body and have nothing to do with air pressure. Option D is incorrect because light energy is also a form of electromagnetic radiation and is not related to fluctuations in air pressure.
