Question

What does Young's experiment prove?

Answer 1

1. Young's double-slit experiment employs two coherent light sources separated by a small distance, usually a few orders of magnitude greater than the wavelength of light.
2. Young's double-slit experiment aided in the comprehension of the wave theory of light, which is depicted in a diagram.
3. As depicted, a screen or photodetector is positioned at a large distance '$D$' from the slits.
4. Young flashed light through two thin slits and viewed alternative bright and dark pattern on a distant screen.
5. The interference of the waves by the overlapping of the waves was observed in Young's double-slit experiment.
6. Light, according to Thomas Young, has a wave character and undergoes superposition.
7. He demonstrated the constructive and destructive interference of light in his experiment.
8. Young's experiment is a proof of light's wave theory.
