Tips to memorize wavelengths of the spectrum
I know we have to memorize the order of the spectrum (microwave --> gamma rays), but we also have to know the wavelengths of each one. Any tips on how to memorize that?

Re: Tips to memorize wavelengths of the spectrum
I thought we didn't need to know each individual wavelength? Just that 400-700 is visible light? Do we have to. memorize each radiation as well as the individual visible light wavelenghts?

I also thought that we only need to identify the wavelengths of visible light, and maybe be able to identify infrared/UV and X-ray.

I thought he also previously stated in his lecture that we just need to know that 400-700 nm is visible light and that violet is 400 nm while red is 700 nm while the middle is yellow and green. He also said we would focus more from microwave to x-ray, but I think for right now, we just need to know visible light.

Re: Tips to memorize wavelengths of the spectrum
I think it is just important to know the overall order, but not specifically the different wavelengths for each other than the range for visible light. One way I remember the spectrum is that from the red visible light (around 700 nm), it is followed by infra"red" which is longer. Then for the the other side of the visible light, I remember that it is violet (around 400 nm), so it is preceded by ultra"violet" which is shorter on the spectrum. Hope this helps!

I don't think we need to know specific wavelengths except that visible light falls under 400(violet)-700 (red) nm. Anything above 700 nm will fall in the infraRED spectrum. Anything below the violet wavelength of 400nm will be in the ultraVIOLET spectrum. Of course there are microwaves and radio waves, which lie past the infrared region in that order. Then there are x-rays and gamma rays, which come past the UV region.
I don't think we'll need to know the specific wavelengths each region falls under, but I think we should know which region falls where in the EM radiation spectrum.

Re: Tips to memorize wavelengths of the spectrum
I was looking to see what we had to memorize. thank u for this !!!!

Re: Tips to memorize wavelengths of the spectrum
I think that we just have to know that the visible region is between 400 and 700 nm and red is 700 while violet is 400. I think we should also know that smaller wavelengths usually fall under ultraviolet and longer wavelengths usually fall under infrared.
