Abstract | A compact disc (CD) serves as a diffraction grating for the study of the dependence of angles of diffracted beams on that of the incident beam from a laser. The demonstration/experiment illustrates the occurrence of different orders of diffraction. Knowledge of the wavelength of the laser permits determination of the groove spacing within ~1% by direct measurement of the angles with a protractor. (Author/MM) |
