Study Notes
Definition of Sound in Physics
- Sound is defined as longitudinal mechanical waves.
- Mechanical waves require a material medium to propagate.
- Longitudinal waves vibrate in the same direction as their propagation.
Characteristics of Sound Waves
- Frequency is the number of complete waves that pass through a point per unit time.
- Frequency is equivalent to the reciprocal of periodic time.
- Frequency is measured in hertz (Hz), where 1 Hz = 1/second.
- Wavelength is a characteristic of sound waves.
- Amplitude is a characteristic of sound waves.
- Periodic time is a characteristic of sound waves.
Types of Waves
- Transverse waves propagate perpendicular to the direction of vibration.
- Examples of transverse waves include water waves.
