- We know that light doesn't need a medium through which to travel because the speed of light is experimentally constant: independent of the movement of the source or detector or the direction in which it travels.
At the time, even though the solutions of the Maxwell equations did not require a medium for the light, physicists used with waves from acoustic to water ones, proposed that the waves of light moved on a medium called luminiferous aether.

Aug 12, 2012 · Does light need a medium in order to travel? Answer. Dominic - This has to do with two theories of physics called quantum mechanics and special relativity. And the question that was troubling physicists about 100 years ago was whether light is a particle or a wave.
We know that light doesn't need a medium through which to travel because the speed of light is experimentally constant: independent of the movement of the source or detector or the direction in which it travels.
Jun 8, 2022 · Light, or electromagnetic waves, are just that, waves in the background electromagnetic fields. You could argue that they indeed have a medium, the EM field. This is similar to sound, which is pressure waves in a substance.
Apr 24, 2017 · Light travels slower in a medium than it does in a vacuum, and the speed is proportional to the density of the medium. This speed variation causes light to bend at the interface of two media — a phenomenon called refraction.
Mar 15, 2024 · Light travels through the vacuum of space at 186,828 miles per second as transverse waves, outside of any material or medium, because photons—the particles that make up light—also behave as waves. This is referred to as the wave-particle duality of light.

Apr 12, 2023 · Light does not require a medium to travel through. In classical physics, it was believed that light waves required a medium called the "luminiferous ether" to propagate, but subsequent experiments, such as the Michelson-Morley experiment in the late 19th century, failed to detect the existence of such an ether.
