If photons go through air>liquid>air, then why it’s velocity remains the same before entering the liquid medium and after exiting the liquid medium.
In: Physics
It is best to not think of photons as little particles but as a ripple in a field (like a ripple in a pond).
That is to say, most of the properties of light are a result of it being a wave, and as a wave, the speed mainly depends on the medium itself.
