About This Product
A coherent light source is aligned with the slits and the pattern is projected onto a screen, where students record fringe spacing before changing the slit spacing and comparing results. For Light And Optics classes, this links slit spacing directly to the fringe pattern; eyes must be kept out of intense beams.
Frequently Asked Questions
Q1. Can the Adjustable Double Slit Diffraction Apparatus be used for Young's double-slit experiment? Yes. It is designed for Young's double-slit interference and related diffraction studies.
Q2. What light source does it need? A suitable coherent light source is normally used to give clear interference fringes, chosen to suit the experiment. No light source is listed with the apparatus.
