Prisms and their uses
« on: 02/12/2004 20:44:53 »
At school we used them to replicate Newton's experiments, I later saw them in SLR cameras, but why did they exist before Newton's light experiments?

I'm assuming he didnt invent them so what were they used for?

I'm just operating from memory here, but I think that it was already known that prisms would break up a beam of light into its spectrum, but Newton was the first to show that the spectrum could be sent through a second prism that would recombine it into a beam of white light. The first optical computer.

Thanks GSM,

were they invented as a type of toy with only one use, to break up white light?  I have only heard of one use for a prism centuries ago and that was Isaac Newton experiments. As they existed before him they must have had some use to be worth the effort, any ideas?
