WebLight travels in straight lines, so if you have to represent a ray of light in a drawing, always use a ruler. Unlike sound waves, light waves can travel through a vacuum (empty space). WebJan 13, 2024 · Though, the individual photons as they travel inbetween the atoms, they do travel in vacuum at speed c. Nonetheless, the denser the medium is, the more interactions the photons have to have to propagate, and the more the speed of light slows down. The simplest picture is that light always travels at the speed of light.
