Used in these demonstrations

Two mini Maglite flashlights with caps removed, mounted horizontally in parallel clamps on a ring stand rod, bulbs illuminated and separated by a few centimeters

Angular Resolution of the Eye

Demonstrates the angular resolution limit of the human eye using two closely spaced point light sources. Students discover that the ability to resolve two sources depends on separation, viewing distance, …

Glass plate supported between wooden blocks on a bench, illuminated by a flashlight mounted in a finger clamp on a ring stand; two polarizing filters lean against lead bricks behind the glass plate

Brewster's Angle

Light reflecting from a glass plate at Brewster's angle ( for glass) is completely linearly polarized. Two crossed polarizing filters placed in the reflected beam demonstrate this: one blocks the …

Full setup: translucent screen at left, multicolor LED tower on stand at center, incandescent light bulb in wooden box at right, with bar clamp, lead brick, and masks on bench

Introducing a Pinhole

A sequential progression from shadow casting through slit projection to pinhole imaging. Students build intuition for rectilinear propagation, image inversion, and the pinhole camera principle by drawing ray diagrams at …

Gray metal stool on a wooden rotating platform, with two blue-handled flashlights inserted through holes in the stool seat

Rotating Table Pulsar

Models a pulsar's lighthouse effect using rotating flashlights. Students learn that pulsars emit continuously but appear to pulse because their beamed radiation sweeps past Earth's line of sight — a …
