- If you're talking about light traveling through empty space, then no, there is absolutely nothing we can do to slow it down. (In fact, special relativity says that even if we run away from a light wave really really fast, it will still be coming towards us with the same speed.

What causes light to slow down? Or: How does it slow down? If light passes through the medium, is it not essentially traveling in the "vacuum" between the atoms?

Jul 24, 2023 · Light slows down when it enters a medium, like glass. This is what is explained in this article. When the light leaves the glass medium and enters air (or, vacuum) it regains its original speed.
Yes. Light travels slower through diamond than it does through glass, slower in glass than it does through water, slower through water than it does through air, and slower in air than it does through a vacuum.
Yes, light "slows down" all the time through different materials other than vacuum. Light's speed in air is nearly the same as its speed in vacuum, so we just consider its speed through air to be the same as its speed in vacuum, c (around 3e8 m/s).
Oct 29, 2024 · The speed of light traveling through a vacuum is exactly 299,792,458 meters (983,571,056 feet) per second. That's about 186,282 miles per second — a universal constant known in...
The speed of light in vacuum, commonly denoted c, is a universal physical constant that is exactly equal to 299,792,458 metres per second (approximately 300,000 kilometres per second; 186,000 miles per second; 671 million miles per hour).

Dec 25, 2011 · Electric and magnetic fields can exist in a vacuum. When an electric field changes, it creates a changing magnetic field, and vice versa. Oscillations between those fields travel at the speed of light through the vacuum. That's the classical view, which does not involve photons.
