Ok. I admit I'm completely new to Relativity (I had my first lecture today!). What I learned was that the speed of light is a absolute constant that doesn't change.
I then came into some situation like,
1. I'm driving my car with velocity v and turn on my headlights, won't the speed of light coming out of my headlights be c+v?
2. If light speed is absolute constant, then the index of refraction would always be 1 when light goes from one medium to the other because index of refraction is the ratio between the speed of light in two different media.
Someone please explain.
