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.
BUT JUST AS IMPORTANT, Mr. Hatfield 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 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 be using that method for the rest of the course, it is important that students master the use of that method for future success.
