Hi there, in this question we're given some different colors of light and we want to know which color is more energetic.
00:08
Well to answer that question i want to talk about a little bit about the electromagnetic spectrum.
00:15
So there are various members of the electromagnetic spectrum, all of them travel at the same speed and that is the speed of light in a vacuum.
00:25
So if we arrange these members of the electromagnetic spectrum in terms of increasing energy as we go across, what we would have down here at the bottom are the radio waves followed then by the microwaves.
00:45
Then we would have infrared radiation followed by visible light, that ultraviolet, x -rays, and gamma rays.
01:05
If we kept going we would also have cosmic.
01:11
All right, but what we're interested in is this region here of visible light.
01:17
If we break that down further to the colors of visible light, that's where we have regibiv...
