Physics of Sound

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.
