WebOct 3, 2011 · Rayleigh waves are formed under the conditions where multiple reflections of P and S waves sum up to make a bigger, slower (group velocity) wave which expands cylindrically. Also, Rayleigh waves are "surface waves", which means that they only propagate at and a few hundred km below the surface (they get weaker with depth). May … WebOct 25, 2024 · Rayleigh’s criterion for minimum resolution : Two overlapping diffraction patterns due to two point sources are acceptably or just resolved if the centre of the central peak of one diffraction pattern is as far as the first minimum of the other pattern.
