Hello and welcome to the forum:

First, if you are confused about variables, Science Buddies has two articles to help you: https://www.sciencebuddies.org/science- ... bles.shtml and https://www.sciencebuddies.org/science- ... test.shtml.

In the background section of the project it describes how to measure the speed of light. Please review this section, and if you still have questions, please come back with a specific question. Please note that this is an advanced project that requires an understanding of trigonometry.

Best,
Keith
