Does electric field lines refract just like light? [closed]
Do electric field lines approaching a boundary at an angle get refracted and change direction just like light rays do?
Because will discussing electric field lines and flux associated with it we do ...

Why does frequent remain constant in refraction? [duplicate]
So at school the told us that:
V= f x λ
In refraction we were told that direction,speed and wavelength changes when a wave crosses different mediums, and on another occasion that frequency is the ...

Confusion regarding light [duplicate]
I have two question about light:
When a light wave travels from free space to a medium then there is a change in the amplitude. Why?
when a wave changes its medium then its frequency does not change ...

How do EM Wave Boundary Conditions Comply with Conservation of Energy?
One of the boundary conditions of an EM wave crossing a boundary (dielectric materials, wave is TE polarized), where part of the wave is reflected and part is refracted, is
$$E+E'=E''$$
where E is ...

Does light change phase on refraction?
I have seen a lot about when light undergoes a phase change when it is reflected. But does it undergo a phase change when refracted and if so why and if not why not?
