Two Kinds of Waves
Transverse (rope)
crest
trough
λ
Longitudinal (spring / sound)
compression
rarefaction
wave → particle ↕
wave → particle ↔
Transverse
rope, light, water
Longitudinal
sound
v = f λ
wave equation
1. Transverse
Particles move up and down, the wave moves forward
Crest (up) and trough (down)
2. Longitudinal
Particles move along the wave direction ↔
Compressions and rarefactions
3. Formula
v = f λ
speed = frequency × wavelength
