A laser reflects off a glass prism through a polarizing filter. Rotating the prism sweeps the reflected beam across the screen; at Brewster's angle the reflected dot nearly vanishes, showing …

A laser illuminates double slits on a Cornell plate, producing an interference pattern on a distant screen. The Cornell plate has multiple slit configurations (varying separation, width, and number of …

Demonstrates single-slit Fraunhofer diffraction using a Cornell plate with calibrated slits of varying widths. Students observe the inverse relationship between slit width and diffraction pattern width, with quantitative verification possible …

Physical models of the three Gaussian surface geometries (spherical, cylindrical, planar) help students visualize these abstract mathematical surfaces. Students develop intuition for selecting the appropriate Gaussian surface based on charge …

A Cornell plate provides multiple-slit patterns and gratings of various densities. Students observe how increasing the number of slits sharpens the principal maxima while keeping their angular positions fixed, and …

Students observe total internal reflection at a water-air interface by sweeping a laser beam through a range of incident angles. The reflected beam visibly brightens as the angle approaches critical, …

Demonstrates double-slit interference with variable slit separation using a laser and PASCO diffraction wheel. Students observe the inverse relationship between slit separation and fringe spacing, providing direct verification of.

Demonstrates single-slit Fraunhofer diffraction and the inverse relationship between slit width and angular spread. Students directly observe that narrower slits produce wider diffraction patterns by rotating through discrete slits from …
