Diffraction Apparatus, Used to map light intensity versus position for many-slit geometries, Slits are made by depositing metal film on glass, creating extraordinarily clean slits with fully opaque blocking areas.
vertically-aligned set LED, easy and dramatic demonstration of the relationship between the color and wavelength of light, spectral range of each LED can be investigated with spectrometer, or just viewed for comparisons with each other
