What is a progressive wave?
A phenomenon from propagation of identical disturbances emitted regularly by a source.
What is the formula relating wavelength , period , speed , and frequency ?
What is a wavefront in wave propagation?
The wavefront is the most advanced disturbance created by the source.
How does a transverse wave differ from a longitudinal wave?
A transverse wave propagates perpendicular to deformation, a longitudinal wave propagates parallel.
Progressive wave Definition
Series of identical disturbances from a source.
Wavelength Formula
λ = T V = V / N.
Wavefront
Most advanced disturbance created by the source.
Wavefront phase conditions
Crest: source phase=0; Trough: phase=π.
Wave types
Transverse: perpendicular; Longitudinal: parallel.
Source equation
y_S(t)=a*sin(ωt+φ_S), φ_S=0 or π.
Point displacement delay
y_M(t,x)=a*sin(ωt-2πx/λ+φ_S).
