Hi, Thanks for the reply all.
Ian I understand what zapper says.
We are already clear that we are not talking about the prism effect which involves light hitting glass at an angle. You twin cyclist analogy describes the prism effect. But in my case here, the twin car analogy described by...
"The emitted photon may encounter other lattice ions as it makes its way through the material and this accumulate the delay."
Doesn't this statement signify that the delay is accumalated over time, which means light slows down gradually through a medium?
In a movie I saw that white light...
So that means light becomes slower and slower until it stops going any further. That explains why light does not reach the bottom of a very deep sea.
Thanx, I overlooked that part. Now it makes perfect sense to me.
So the first color of light you see when you are ascending from deep scuba...
Ok thanx, that reply satisfies my question.
Now I've got a second question,
Does light drop to a certain speed instantly when it hits glass and remains at that speed until it exits, or does it become slower and slower while it is traveling through glass?
Thanks for the link. But that posts doesn't fully answer my question. When incident light hits glass at a perpendicular angle, it does not refract but it still slows down.
So does red exit first before violet at the other end? How will it look like? Because there is no bending and hence no...
Does perpendicular incident light slow down through glass? When light travels through glass at a perpendicular angle, there is no refraction and hence no bending. If it slows down through glass, does that mean that red will emerge first and violet last?
Have you come across different interrelated subjects that talk about the same thing in essence, but each subject alone by its own individual frame of reference cannot give you a full perspective or complete picture to understand the matter in focus? You really wish you could learn something in a...
