video - Interference and DiffractionPurpose:Shine a laser beam through single, double and multiple slits of different widths and spacing on a Cornell multiple slit film.Procedure:    Set the stand so that the different patterns can be projected onto a wall or screen. The film holder can be moved in X & Y and secured by two thumbscrews to hold different patterns steady. On the film there are four different columns of slits. The first of these is a series of single slits varying in width. The second is a continuously varying single slit that gradually resolves itself into a varying double slit. The third and fourth sets are of multiple slits of various spacings. The middle pattern in the third row has the most slits, thus giving the sharpest interference pattern. The fifth is a series of double slits of the same width that vary only in their spacing. Hints:
