Slowing down light
WebbYes, 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). Light is an electromagnetic wave, and the materials through which it travels make up a ... Webb11 feb. 2024 · by Andrea D. Steffen February 11, 2024. A scientist at NASA proves that the speed of light is torturously slow through 3 simple animations. His clever physics animations show how long it takes light to travel around the Earth, from Earth to the moon, and from Earth to Mars. You can really see just how fast (and slow) the speed limit of the …
