λ (lambda) is the wavelength — the distance between successive identical points on a wave (e.g., crest to crest).
Related variables:
- f = wave frequency (number of cycles per second), unit: Hz.
- T = wave period (time for one cycle), T = 1/f, unit: s.
- v (or c for light) = wave velocity (speed the wave pattern moves), unit: m/s.
Key relations:
- v = f · λ
- f = 1/T
- angular frequency ω = 2πf, wave number k = 2π/λ, so a travelling sinusoidal wave often written as y(x,t)=A sin(kx − ωt + φ).
