Thanks for the clarification; that's what we were thinking. Just to make clear what I meant, I wasn't referring to the colour of the light after leaving the glass as that's obviously trivial.

Does the light have a colour if it isn't being observed? This is the difficulty we faced when trying to establish whether the light would change colour. Given that in this thread there are differing opinions, I'm glad to know my teacher and I aren't alone in being a little bit unsure.

I'm not referring to how some wavelengths are refracted more; rather, I'm talking about the behaviour of a specific wavelength of light when it enters glass, and whether it changes 'colour', as we know it.

We know that the wavelength of visible light changes when it travels between two media with different refractive indices. Here's my question: does light change colour when it moves from air into glass? I had quite an interesting but inconclusive discussion about this with my Physics teacher...
