The filter may be arranged with a light source and a pair of small projection screens so that the colors of the transmitted and reflected light are simultaneously visible.

Various slit widths and spacings are available. The experiment may be done simultaneously with red and green lasers to show the effect that wavelength has on the patterns. text/html 2023-03-23T13:33:44+00:00 Anonymous (anonymous@undisclosed.example.com) https://physlab-wiki.com/physicsdemos/waves_and_optics/interference/laser_multiple_slit_interference?rev=1679592824&do=diff Laser Multiple Slit Interference Laser light is shone though a multiple-slit mask and the resulting interference pattern is viewed on the wall or projection screen. The number of slits used may be sequentially varied from two to five. The interference pattern resulting from a diffraction grating may be simultaneously shown for comparison. text/html 2021-11-05T16:44:18+00:00 Anonymous (anonymous@undisclosed.example.com) https://physlab-wiki.com/physicsdemos/waves_and_optics/interference/newton_s_rings?rev=1636145058&do=diff Newton's Rings Two slightly convex pieces of glass are pushed together with an adjustable clamping apparatus. The interference pattern that results may be viewed in reflection.

Interference fringes result from the combination of light reflected off of the two air/liquid interfaces formed by the soap film.
