When monochromatic light is incident on a surface separating two media, the reflected & refracted light both hav the same frequency as the incident frequency.Cud u explain in detail 'why'?
I don't know much about this at 12th level.But a very basic approach is as follows.
Monochromatic light = Light of a particular single color = Light of a certain wavelength.
wavelength is inversely proportional to frequency.So frequency depends only on wavelength
So frequency will change only and only when wavelength changes.
But a monochromatic light comes out as such in both refraction in reflection.So frequency doesn't change because wavelength has not changed.
Thanks.Hope you got it and please tell me whether its correct or not.And if you get a good answer (detailed or high level answer) for this please do notify me.
