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.

Recall the formula for beat frequency and find out what frequency actually sound

what is part b asking us to figure out? what equation should we be using since specific tension isn't given?
hi, i tried the formula abs(f1-f2) for beat frequency but i can't get the answer for part a. do the harmonics have something to do with how you get the answer?
I didn't use any equation I just put 2 for second harmonic since it says "The tuner can determine this by listening to the beats between the third harmonic of the A and the second harmonic of the E". I doubt that's the right way to do it but it accepted it. does anyone know how to do part B?

For part b you have to use original frequency for tone E not the higher harmonics
