Study Notes
Wave Properties
- Electromagnetic waves do not require a medium to travel through.
Wave Characteristics
- Amplitude is the property of a wave related to its loudness.
Speed of Sound
- The speed of sound in a vacuum is approximately 299,792,458 meters per second (m/s) or 299,792 km/s.
Frequency and Period
- The term for the number of complete waves that pass a certain point in one second is frequency, measured in Hertz (Hz).
Sound Propagation
- Sound travels fastest through steel due to its high density and stiffness.
Pitch and Frequency
- When the frequency of sound waves increases, the pitch of the sound also increases.
