### Memorizing Wavelengths

Would it be optimal to memorize the wavelength regions radio--->gamma? Or would that be a waste of time?

I believe it would be helpful to know, just in case. I think it'll help to have a general idea of how large each type of electromagnetic wave is (especially to know visible is between 400 and 700 nm, for example), if only to help you double check your work on the test. Hope that helps!

I asked my TA, and they said we should know that visible light comes from 400 nm (red) to 700 nm (violet), and know what comes right before and right after (infrared is around 10^-4 to 10^-6 and X-rays are around 10^-8 to 10^-10)

I think it would be helpful to know the order how large the electromagnetic wave is.It would help to know the increasing wavelengths and frequency just remember that they are inverse to one another

It definitely wouldn't be a waste of time, it could even save some time on tests/midterms. Also by memorizing wavelengths you can easily find the frequency with the speed of light equation so memorizing one is like memorizing both.
