The length of a soundwave at 20Hz is 56.26 ft.
The length of a soundwave at 20Khz is 0.67 inch.

What's the speed of sound in air?
What's the frequency of the sound in question?
How do I determine the wavelength of said sound travelling through said medium? It's right there in your text book.

sound travels at 380m/s or 1050ft/s in air.
The general expression is c = fw where c is the speed of sound, f is the frequency and w is the wavelength.

- Close, but jeztyr is closer, gmeades is dead on. There is a lot of relativity going on, barometric pressure, air temperature. For instance, I can say sound travels at 1130ft/s, and that would tell you the two facts of relativity, that I am at sea level and that it is 68 degrees F where I am. 1 degree in fluctuation in either direction results in a change of 1.1ft/s. I'm not sure the change you get by altering the barometric pressure. But wavelength is dependent on none of these factors.

I can hear when a TV is on (muted) from across the house-I googled and apparently I hear at a higher frequency than most (+15,000Hz). I am wondering how common of a trait this is in humans, why (medically) can I hear this, is it a "defect"?
