In this VIDEO, Mr. Hatfield models calculations that allow students to determine the frequency and the energy of a particular light wave seen in spectroscopy, as discussed in Section 4.2 of our text, and as seen in the Bright Line Spectra Lab.
BUT JUST AS IMPORTANT, Mr. Hatfield AGAIN models the use of a notation for displaying very large or small numbers that mimics with the 'EE' key found on many scientific calculators.
This method was previously taught in class. It is a SUPERIOR method that saves time, reduces the likelihood of student error and has students writing out these numbers in a form that matches the way they enter those numbers into a calculator!
And, since students will continue to use that method for the rest of the course, it is important that students master the use of that method for future success.
