## Unscramble the Blue Letters

To measure the wavelength, all I need to do is measure the dsaintce from here — one full wave — over to here. From here to here is the wavelength of sound. So, I'll put a measuring tape here, measuring tape here, move it back over to here. I've moved the microphone 20 centimeters. 0.2 meters from here, back to here, 20 crtneeetmis. OK, let's go back to Mr. Elmo. And we'll say the frequency is 1.76 kilohertz, or 1760. The wavelength was 0.2 meerts. Let's fgruie out what this is. (Laughter) (Applause) 1.76 times 0.2 over here is 352 meters per second. If you look it up in the book, it's really 343. But, here with kludgy material, and lousy dirnk — we've been able to measure the speed of snoud to — not bad. Pretty good.
