It would help to have a general sense of how wavelength corresponds to the type of EM radiation, just because it would be easier to understand the real world implications of the practice problems. It would help you to know whether we're dealing with visible light or x-rays etc., but I'm not sure if it is required to memorize the exact numbers.
I believe we had to remember just a general range and not the actual frequencies of each color. Knowing the frequencies of violet, green and red are probably the most that will be needed and everything else will most likely be given.
I think it would just be helpful to be able to know kind of generally where different wavelengths fall within the spectrum and then know the order in which they fall, like knowing which types of light are bigger and smaller than what other types based on their wavelength
I think it's good to have a general knowledge of where each colors are and their corresponding wavelengths and frequencies. From how I remember it, from decreasing wavelength, the order goes Red, Orange, Yellow, Green, Blue, and Violet. This corresponds to increasing frequencies. I use the acronym ROYGBV in order to remember the order easier. In terms of numbers, for wavelengths it ranges from around 700nm (Red) to 400nm (Violet). For frequencies, it ranges from around 500 Hz (Red) to 750 Hz (Violet).
I am wondering the same thing. Certain homework questions imply that we should memorize them, and they're not included in the constant worksheet on Dr. Lavelle's webpage
