### Wavelengths of Electromagnetic Radiation

What is a good way to remember the categories of electromagnetic radiation?

You can remember it by the pneumonic:
Raul's Mother is Visiting Uncle Xavier's Garden
Radio, Microwave, Infared, Visible, UV, X-ray, Gamma Ray
This follows the electromagnetic spectrum in order from decreasing wavelength (and increasing frequency).

Should we be expected to memorize the range of wavelengths for each of the types of electromagnetic radiation?

I think the most important wavelengths we have to memorize refer to the visible light region ranging from 700nm to 400nm. 700nm refers to red light which has a longer wavelength and lower frequency than violet light(400nm).
