Light Reflection/Refraction-

[texan2414]

We know that whenever light hits a surface, some light is refracted into the medium and some is reflected back.

My question is for both the reflected and refracted light rays, which of the following parameters change:
- frequency.
- wavelength.
- wave speed.
- all.

I may be incorrect but I think it is:

Reflected: None
Refracted: If the "n" (index of refraction) changes, then speed changes. Frequency is CONSTANT. Thus, wavelength must change.

Thanks justadream,

I knew about the refracted rays but not sure about reflected one myself.
