Atomic Spectra Online Module Question

Postby Gabrielle Schwab 1G » Thu Oct 08, 2015 7:23 pm

I watched the online module video for the Atomic Spectra. For one of the pre and post video quiz questions, I was able to figure out the answer by the process of elimination. However, I was wondering how to do the first part of the following problem if it weren't a multiple choice question. It says, "What is the wavelength of Krypton-86 radiation? What region of the spectrum is it in? What is the energy of the photon?" I can do part 2 and 3 but I don't know how to start the first question.

Thank you!!

According to the problem, 1m= 1,650,763.73 wavelengths so
1 wavelength = 1/1,650,763.73m = 6.058 x 10^-7m = 605.8 nm
