Students will be able to
- identify the diffraction of a light wave as a change in its direction of travel that does not occur due to changes in the medium in which the wave travels,
- qualitatively describe the interference pattern produced by double slits in terms of alternating light and dark fringes symmetrical about a central bright fringe,
- qualitatively describe the path length conditions for constructive and destructive regions in overlapping waves that diffract through double slits,
- qualitatively relate the angle that light waves spread out after passing through a single slit to the ratio of the slit width to the light wavelength,
- qualitatively relate the angle that light waves spread out after passing through a single slit to the wavelength of the light.
