Welcome to PHY 121 Blog Help. Here's how it works. For each homework question and lab report we will make a post, this will probably contain a few tips on what the problems are about and how to solve them. If you are stuck on something then instead of emailing us directly you should post a comment in reply to the relevant post. We will try to guide you through tough points and help you understand the problems and the concepts behind them.

Dear Professor,
Where is the review material for exam 2? The echo is not posted on blackboard yet.
It keeps telling me that my answer is wrong for Part C, but I don't understand why. I multiplied wavelength times frequency and put my answer in and it keeps saying "Try Again."
Perhaps the problem with the rounding off. Try to carry through calculation using more significant numbers from a) and b) and round off at the very end
