Ranges in Electromagnetic Spectrum

[Joana Fang 1K]

Are there set ranges that classify the ranges that different types of waves fall under or is there some grey area? If someone has a good picture/resource, could you post it?

The ranges are a bit fuzzy, especially the visible region (some people can actually see frequencies that others can't). It's just difficult to neatly divide a (mostly) continuous spectrum into chunks. This is why we say that the visible region is between about 400 and about 700nm; this is a handy rule of thumb, but is not totally accurate.

However, Wikipedia has a nice graphic that lays out the different types of waves: https://en.wikipedia.org/wiki/Electromagnetic_spectrum#/media/File:Electromagnetic-Spectrum.svg

yes of course!
