What does the wave created during refraction look like?
People always describe refraction as light stimulating the electrons in the glass, which create their own light, which interferes with the original wave. They always say “the math is too complex, but ...

Path a photon or phonon takes in a moving medium
Lets say we have a medium with refractive index n whose velocity is given as a function of height.
$v_x(y)=ay$
How would we go about finding the motion of a photon or phonon in this space from the ...

Reconciling refraction with particle theory and wave theory
I have searched the web for good answers to why refraction occurs when light moves from one medium to another with different density. I have limited background in physics and want to know if there is ...
