About This Product
Light passing a narrow slit does not simply cast a sharp-edged strip; it spreads and forms bands, which is direct evidence of its wave nature. Students mount the slide in the beam, move the screen and watch the pattern change, then relate what they see to diffraction theory.
Frequently Asked Questions
What does the 1 Slit Slide show?
With a light source or laser shining through the single slit, a diffraction pattern and the spreading of light appear on a screen placed behind the slide.
