Specifics on Light

[Natalie Do 3F]

On question 1.5 on the bookwork, it asks to order different types of light by energy. Should we memorize the order of light wavelengths (radio, micro, infrared, visible, ultraviolet, x-ray, y-ray, cosmic, etc) and know their approximate wavelengths?

[Crystal Pan 2G]

Yes, we should know the relative regions and order for the test, because that will not be given to us.

[Sandy Lin 1L]

yes, we should def know the order, and it is most important to know that visible light ranges from 700nm to 400nm. For the other ones, it's good to know the approximate ranges too just in case it asks you where it falls on the spectrum.

[Veronica Macias 3K]

It might be helpful to look up a mnemonic for the electromagnetic spectrum so it is easier for you to memorize the order. The one that worked the best for me is "Raging Martians Invaded Venus Using X-Ray Guns" but there are other ones !

[Ann Cosico 2H]

Yeah I think it would be pretty important. I think it would also help to look at examples of each type of wave! For example, you would know that xrays are completely different from something like radio/tv/microwaves.

I think we should be familiar with the electromagnetic spectrum for the final. Knowing what values are in the different regions.
