minus-squareGlowstick@lemmy.worldlinkfedilinkEnglisharrow-up1·2 months agoActually, c is the speed of light in a vacuum, but light travels slower through a medium, like air. So lasers shot through air will actually travel slower than c.

minus-squareASeriesOfPoorChoices@lemmy.worldlinkfedilinkEnglisharrow-up1·2 months agoexactly where they should be.
minus-squaremarcos@lemmy.worldlinkfedilinkEnglisharrow-up0·2 months agoA laser strong enough to be used as a weapon will probably not leave a lot of medium on its path. But the front-most part will still travel at less than c. It will just speed-up after a while.
minus-squaresinkingship@mander.xyzlinkfedilinkEnglisharrow-up0·2 months agoI’m curious. What happens to the medium? Does it simply get pushed aside? Or pushed along? Or will it eat up some energy and react to something else?
minus-squareTlaloc_Temporal@lemmy.calinkfedilinkEnglisharrow-up1·2 months agoMuch like lightning, a powerful enough laser will ionize the air. That ionized air is hot and rises, just like the ionized gasses from combustion. A powerful laser will look like a beam of fire.
