SUMMARY
Passing light through helium-3 does indeed slow it down, as light travels at different speeds in various media. The speed of light in a vacuum remains constant at approximately 299,792 kilometers per second, but when light enters helium-3, it experiences a reduction in speed due to the medium's refractive index. This phenomenon is consistent with the behavior of light in other substances such as air, water, and glass. Understanding this principle is crucial for grasping the fundamental concepts of optics and light propagation.
