This program simulates the motion of a series of straight waves as they are reflected, refracted, diffracted and interfere.  For reflection and refraction you can alter the wavelength and the angle of incidence.  For refraction you can also alter the refractive index. Diffraction by a sharp edge and by a gap can also be investigated as can two-source interference and the Doppler effect on waves from a moving source.  The printouts are particularly useful as they give accurate diagrams of how the waves behave
