Unscramble the Blue Letters
To measure the wgtnaelveh, all I need to do is measure the distance 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 mnorhpocie 20 centimeters. 0.2 meters from here, back to here, 20 centimeters. 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 meters. Let's figure out what this is. (Laughter) (Applause) 1.76 times 0.2 over here is 352 mteres 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 sound to — not bad. ptrety good.

To measure the __________, all I need to do is measure the distance 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 __________ 20 centimeters. 0.2 meters from here, back to here, 20 centimeters. 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 meters. Let's figure out what this is. (Laughter) (Applause) 1.76 times 0.2 over here is 352 ______ per second. If you look it up in the book, it's really 343.
