Yes, Thomas Young is credited with conducting the famous double-slit experiment, which demonstrated the interference patterns of waves. Young performed the experiment in the early 1800s to study the wave nature of light.
In Young's experiment, he used a screen with two narrow slits and allowed light to pass through them onto a second screen placed behind. He observed that when light passed through the slits, it created an interference pattern of alternating light and dark bands on the second screen. This pattern could only be explained if light exhibited wave-like behavior and experienced interference.
Young's experiment provided strong evidence in favor of the wave theory of light and contributed significantly to the understanding of the wave-particle duality of light. It played a crucial role in the development of the field of optics and laid the foundation for later experiments and the formulation of wave optics and quantum mechanics.
