Final answer:
In a double slit experiment using very low light levels, it demonstrates the wave behavior of light. When light passes through the double slits, it diffracts, creating an interference pattern of bright and dark fringes. This experiment shows the wave-particle duality of light.
Step-by-step explanation:
In a double slit experiment using very low light levels, it demonstrates the wave behavior of light.
When light passes through the double slits, it diffracts, which means it spreads out and creates an interference pattern on a screen. This pattern consists of alternating bright and dark fringes. The bright fringes are regions of constructive interference, where the waves from the two slits reinforce each other, while the dark fringes are regions of destructive interference, where the waves cancel each other out.
This experiment is a key demonstration of the wave-particle duality of light, showing that light can exhibit both wave-like and particle-like behavior.
