# Waves

## Longitudinal and Transverse Waves

Longitudinal - direction of motion parallel to wave
Transverse - direction of motion perpendicular to wave


## Wavelength & frequency


$$v=f \times \lambda$$


Nodes - point of no motion
Antinodes - point of maximum motion (peaks)

Crests (peaks) & troughs (azimuths)



## Interference patterns

Standing wave - constructive interference at resonant frequency
