4. Diffraction : Educating Physics
To understand and interpret graphical representations of transverse and longitudinal waves (i) diffraction of all waves (you will be expected to know that diffraction effects become significant when the wavelength is comparable to the gap width) (ii) techniques and procedures used to demonstrate wave effects using a ripple tank

Diffracted seismic waves are generated by an anomaly including the boundary between layers, faults and fractures, and the results of FWI and RTM depend on the diffraction angle between...
We now turn to a consideration of what happens when two light waves interact with one another. We assume that the intensities are low enough that the disturbances add vectorially. The question then becomes whether the two waves are in phase or out of phase. There are basically four ways in which the waves can get out of phase. 1.
diffraction. An incident plane wave or spherical wave (which, like a plane wave, has a flat and well-behaved wave front) is required to see diffraction. Here, rays from a point source yield, in principle, a perfect shadow of the hole, allowing diffraction ripples to be seen. Screen with slit
