Does anybody know anything about Prisms and light refractions?
I'm asking this questions based on the video "Newton's Prism Experiment" on YouTube on the Channel "MITK12Videos".
In the video, he showed very clearly how a white beam of light is actually the sum of the colored spectrum, but what was most impressive was when he used a second, more specifically shaped prism to show how the distance from the wall the beam eventually hit effected what order the colors were in. They would be inverse at a certain point.
So my question is, does anybody know where the clearest form of this kind of information and experimenting around prism, light and mirror themed topics can be found? Preferably something as good for a layman as for a physics enthusiast, as in the video I brought up, and that would take this line of inquiry to its highest possible conclusion.

Yes, but not with prisms. The most obvious example in nature is with raindrops and double and triple rainbows. This is BOTH refraction and reflection. The first rainbow is the brightest and has the ROYGBIV color order. The second outer rainbow is not as bright and has a reverse color order because it is a reflection. The third rainbow is fainter and the familiar color order.
This also happens with halos around the Moon because of ice crystals, usually in the stratosphere. Yiu may be able to see only the red of the outer edge of the the first halo and the red inner edge of the fainter second halo, or the halos may be just be white. https://addins.wvva.com/blogs/weather/2015/05/rain...
