Problem 47P

What is sound? How is it generated? How does it travel? Can sound waves travel in a vacuum?

Step-by-Step Solution:

Step 1</p>

a)Sound is a form of energy produced and transmitted by vibrating matter.Material medium is required for the sound wave propagation.

Step 2</p>

b) Sound waves are always generated when an object or medium vibrates.

Sound travels in waves. When sound moves through matter (solid, liquid, or a gas), the molecules of the matter move backward and forward in the direction in which the wave is traveling. This movement is called a vibration.
