Wave motion, Transverse and longitudinal waves.

Elaboration of Syllabus:

Transverse and longitudinal waves; characteristics of a harmonic wave;
graphical representation of a harmonic wave. Distinction between transverse
and longitudinal waves; examples; displacement, amplitude, time period, frequency, wavelength, derive v=fλ; graph of displacement with time/position,
label time period/wavelength and amplitude, equation of a progressive
harmonic (sinusoidal) wave, y = A sin(kx±ωt) where k is a propagation factor
and equivalent equations.
