All right, so it looks like you're to do a report on this debate that went on for hundreds of years of what light actually was.
00:13
They used to debate that it was either a particle or a wave.
00:18
And before thomas young, which we're supposed to not include in your report, the main idea was that light was a particle.
00:30
It bounced off things.
00:32
It was similar to any other particle that we would see.
00:39
So isaac newton had done quite a bit of research with what light was composed out of, and he was able to conclude that there was the spectrum that existed.
00:51
He used a variety of different prisms of glass and other materials that would show that you could split the white light into components.
01:03
Well, that should have been proof that light was a wave, but they ignored that property.
01:11
They explained it away in a different way.
01:14
You'll want to, when you make your report, i would start by looking online for some good references to look at the history of what isaac newton did in the work he did with the spectrum.
01:30
He did all kinds of great.
01:31
Things and one of them was understanding how prisms can cause light to break down into its components.
01:43
So he definitely did some great things when it came to our understanding and what light was.
01:49
He just misinterpreted what these color bands were doing.
01:54
So you want to look into that in more detail for your report.
01:57
Another idea that was already out there that should have shown on that.
02:02
What light was acting as a wave was the use of mirrors.
02:07
So here we have some old mirrors from the 1700s that were made for focusing light, making it brighter in a room or magnifying so that make it be used and such.
02:24
But they were used in scientific ways as well.
02:27
But here we have a contave and convex mirror...
