Document Summary
Physics of light: light as a wave and its interaction with matter iii. Diffraction of waves: diffraction: the behavior of a wave when it encounters an obstacle or a non-uniformity in its medium. May 29 to may 31st: different parts of the wave(s) (crests, troughs, etc. ) will interfere (merge) with each other, producing brighter and darker areas, propagate outward. Interference: let"s look in more detail at one of the behaviours of light in diffraction interference of waves. Interference: the superposition of two (or more) waves resulting in a new wave pattern. two incoming waves they are coherent: are. Alig: these with each other"s patterns of crests and troughs. Or, we say that the waves are in-phase with each other: ned": these two waves are incoherent, or out of phase with each other. More specifically, these two waves are completely out-of-phase with each other (the crests and troughs are.
