I guess that would be it if any other problem do ask I am willing to answer
Each colour of either it is red yellow blue any 7 one of the seven colour when emerges from prism will all have different wavelengths
i know that but we see all these 7 colours in air as white light
in air all these colours have the same speed.my ques is that why don't we see white light when all these colours emerge out of the prism.in the prism,all the colours bend to different amounts because of their different speeds in glass
According to me we can see the white light
If we perform this experiment in a dark room with one beam of light we see the light
You get it??
actually we see a spectrum of colours when we perform this activity.and i am asking why this happens
can we talk about tgis a little later. right now i am studying total internal reflection in a prism
Ya sure
