5.0 Sound and Waves

Defining the WAVE

• Disturbance propagating through spafce
  • Containing ENERGY not matter

Propagation

• The DIRECTION of motion

Types of Waves

Transverse

• Waves move PERPENDICULAR to the disturbance

Longitudinal

• Waves move PARALLEL to the disturbance
• Illustration:
  

Sound Wave

• A type of pressure wave (MUST pass through a medium $\ne$ travel in a vacuum
  • A LONGITUDINAL wave

Parts of a Transverse wave

Useful Formulas

• $T=\frac{1}{f}\to f=\frac{1}{T}$
• $v=\frac{\lambda }{T}\to =f\lambda$ - this is the universal wave equation
