Which experiment attempted to detect the existence of "aether wind"?

The Michelson-Morley experiment is significant because it was specifically designed to detect the presence of "aether," a medium that was hypothesized to carry light waves through space. At the time, physicists believed that light required a medium for transmission, similar to how sound travels through air. The concept of "aether wind" referred to the idea that Earth's movement through this aether would create a detectable shift in the speed of light depending on the direction of the light's propagation relative to this wind.

The experiment utilized an interferometer to compare the speed of light in perpendicular directions. If the aether existed and the Earth moved through it, the speed of light would exhibit differences depending on the direction of travel relative to the aether wind. However, the results of the experiment revealed no significant difference, providing strong evidence against the existence of the aether and shaping the foundation for Einstein's theory of special relativity.

In contrast, the other experiments listed do not relate to the detection of aether. The photoelectric experiment focuses on the interaction between light and matter, demonstrating the particle nature of light. The double-slit experiment illustrates the wave-particle duality of light and particles, showing interference patterns without addressing aether. The Stern-G
