Wavelength and Type of Light

Postby Petrina Kan 2I » Sun Nov 03, 2019 2:16 am

For the midterm, do we have to memorize the cutoffs for what wavelength corresponds with what type of light? For example, how visible light is a wavelength of 400-700nm. Do we have to know this for all the different types of light?

Hi,
Yes you should know the cutoff for visible light and perhaps UV light but when I went to the TA review session he said don't worry too much about this as most problems are going to ask you to solve and knowing all the ranges of light is a little too specific

I would assume that we won't need to know it for all types except for visible light.

You should know the range in nm for visible light (700-400) and also the colors associated with each end of the spectrum (red for values closer to 700nm and violet for values closer to 400nm). As for the other ranges on the electromagnetic spectrum, you should generally know the order of EM radiation based on order of increasing energy: radio, microwave, infrared, visible, ultraviolet, X-rays, gamma rays.
