Matching Wavelength to Type of EM Radiation

Postby Alexa Mugol 3I » Mon Oct 14, 2019 4:49 pm

In problem 1B.15, we're asked to calculate the energy to remove an e-, then calculate the wavelength associated with it, and then name the kind of EM radiation used. I was able to do the first two, but I had to look back in the textbook reading to match the wavelength to the type of EM radiation. Are we supposed to memorize which types of radiation correspond to which wavelengths?

Lavelle has said that we don't have to know all of the specifics, but know that visible light ranges from 400-700 nm, and radiation with more energy (UV, gamma rays for example) has shorter wavelengths (<400) and radiation with less energy have longer wavelengths.

We only have to know the general range (700 nm to 400 nm).
