### Memorization of Electromagnetic Spectrum

For this course do we have to have all the values in the electromagnetic spectrum memorized?

A UA told me we have to memorize the order of the spectrum. And for visible light know that violet has the shortest wavelength while red has the longest.

In addition, it's probably noteworthy that visible light exists at around a wavelength of 500 nm and that the human eye detects EM radiation (visible light) within the 700 nm (red light) to 400 nm (violet light) region.

I agree! I think that it is important to have a general understanding of which ends of the spectrum red and violet light fall on. Additionally, during a step-up session, it was mentioned that it would be useful to know the order of different kinds of waves from shortest to longest (gamma rays, x-rays, ultraviolet rays, visible, infarred, radio).
