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.
Find the two times and its difference. 1) Sound hitting you directly (remember you are in the middle. and they give you distance ) 2) Sound hitting the wall first and then back to you.

Is this guy posting an answer key somewhere? What's going on with that?
V = Distance/ Time
