A saxophone is playing a steady note of frequency 266 Hz. The temperature in the room is 25 C. Suppose that at some instant the varying pressure at your eardrum is at a maximum. How far away in meters is the next pressure maximum?
The answer is 1.3.

The distance between the pressure maximum is an integer number of wavelength. Therefore the shortest distance is the wavelength. The speed of sound at 25 C is 346.33 m/s. Then we can find the wavelength:
L = v/f = 346.34/266 = 1.3 m
