11 июл. 2011 г. · Here's something awesome! Basically says it is not because photons are absorbed and reemitted, but it is because of collective behavior.

27 мар. 2014 г. · Vacuum = no friction = no electromagnetic interference = faster, for both matter AND energy. Light appears "slowed" in matter because the waves ...

6 окт. 2019 г. · Light travels faster in vacuum than through air, so is there a material that could slow light down in a way that we could see it traveling?

4 окт. 2012 г. · Light will necessarily travel at that speed because it has no mass. It doesn't need to be propelled, and there is no mechanism behind it.

5 дек. 2022 г. · Light happens to be massless, so it always moves at the speed c. This is why c is more typically called "the speed of light".

10 окт. 2019 г. · The speed of light isn't just a speed limit for photons, it's the only speed they can physically travel at (in vacuum).

6 сент. 2015 г. · No, speed of light is determined by the permeability and permitivity of free space, in a medium these arent the same as in a vacuum so the speed ...

30 мар. 2024 г. · Technical answer: the electric and magnetic force constants. Deeper answer: all massless waves propagate at the same speed, what we call the speed of light.

28 янв. 2022 г. · A true vacuum will have zero particles in it, which means it's the fastest possible medium through which light can travel.

8 нояб. 2024 г. · It stated in the vacuum because light has unique known properties, fixed speed being one, in a vacuum. Otherwise light will interact with particles in complex ...
