Sound
1. Sound
Sound is a form of energy that produces the sensation of hearing.
It is produced due to the vibration of objects.
Example:
Sound is produced when a guitar string is plucked or a bell is struck.
2. Production of Sound
Sound is produced when an object vibrates.
These vibrations make the surrounding air particles vibrate, and sound travels through the
medium.
3. Sound Needs a Medium
Sound cannot travel in vacuum.
It requires a material medium such as:
solid
liquid
gas
4. Sound as a Longitudinal Wave
Sound travels in the form of longitudinal waves consisting of:
compressions (high pressure regions)
rarefactions (low pressure regions)
