Educational Light Interference Observation Box for High School Physics

This physics experiment kit is designed for high school classrooms to help students visualize wave optics concepts through direct observation. The light interference observation box allows users to project and analyze wave patterns. It features a white receiving screen with a printed millimeter scale, a black base stand, and an optical body with a front adjustment knob and power switch. Includes multiple slide inserts with different slit and opening patterns to demonstrate single-slit and double-slit phenomena. Screen dimensions: 13.5 cm x 8 cm x 12 cm; optical body dimensions: 6 cm x 7.8 cm x 5.2 cm.
