Please Explain Me Refraction of light !
Helo everyone,
I have gone through my textbooks which only comes to the conclusion that since the light travels at different velocity in different medium so it bends at the interfaces. This is something i can't really understand. It doesnot make anything clear to me. I have searched this forum for help regarding this. what i get is this
->" Speed of photons is same i.e C and it is a apprent decrease in velocity"
Whatever it is how does that leads to bending?
->Then to explain snell's law i got another fermat's law which again does not seem to help me. It says light has to travel the shortest path but why should it ?
I guess there are other theories or better explanations at the atomic level.
Pls help me.
And again even if there's some theory to learn in order to understand this why should the textbooks for undergraduate level assume that everyone is just going to mug up this bending phenomenon.(Since it doenot give more explanations)
Thanks
Sorry for my english...
