Finding Wavelength from Diagram

Finding wavelength from a diagram

Transverse Wave

Wavelength is the distance between two successive crests or troughs.

Longitudinal Wave

Wavelength is the distance between two successive compressions or rarefaction.

Wavefront diagram

Wavelength is the distance between two successive wavefront
