Practice calculating redshift for the following. The formula for calculating redshift is as follows:

Here is a practice problem. Important: When doing the calculations you may get numbers such as 3.258293. Round them to second decimal place, like 3.26.

Make sure you figure out how to get the correct answer because on your next quiz, you will be asked to solve some redshift calculations.

1. Observed wavelength is 649.188, expected wavelength is 648.976.
