Question

Sound travels as longitudinal waves and has a region of ____ and ____
(the correct answer gets brainliest and 5 stars.)​

Answer 1

Answer:

Sound travels as longitudinal waves and has a region of compressions and rarefactions.

Explanation:

Longitudinal waves have compressions and rarefactions. compression is a region in a longitudinal wave where the particles are closest together. A rarefaction is a region in a longitudinal wave where the particles are furthest apart.

Answer 2

Sound travels as longitudinal waves with compressions and rarefactions in its region.

• The use of a sine wave to represent sound is only an attempt to demonstrate the sinusoidal nature of pressure-time changes.
• Do not assume that sound is a crestless and troughless transverse wave. In the presence of compressions and rarefactions, sound waves flowing through air are certainly longitudinal waves.
• The particles of air do not vibrate in a transverse manner as sound travels through air (or any other fluid medium).
