Final answer:
The double-slit experiment results support the wave theory of light and the wave-particle duality of light.
Step-by-step explanation:
The results of the double-slit experiment include:
1. Waves produced a diffraction pattern: When light or electrons pass through the double slits, they create an interference pattern, which is a hallmark of wave behavior.
2. Results supported the wave theory of light: The interference pattern observed in the experiment provides evidence for the wave nature of light.
3. Results supported the wave-particle duality of light: The double-slit experiment demonstrates that light has both wave-like and particle-like properties.
