Study Notes
Sound Waves
- Sound is a form of energy that vibrates and travels in waves, similar to light.
- When an object vibrates, such as a guitar string, it pushes molecules together, creating an area of high pressure.
- This high-pressure area is known as the compression part of a sound wave.
- As the vibrating object moves in the opposite direction, it creates an area of low pressure where the molecules are not pushed together, forming the rarefaction part of the wave.
Learn about the speed of sound, its properties, and how it travels in waves through compression and rarefaction.
