Standing Waves in a Bugle

    1. The problem statement, all variables and given/known data
    By adjustin her lips correctly and blowing with the proper pressure, a bugler can cause her instrument to produce a sequence of tones, amog which are the following: 440, 660, 880, 1100, . . . Hz --- all without changing the length of the air column. (b) What is the ffective length of this bugle? (use 346 m/s for the speed of sound in air).

    2. Relevant equations
    2L = v/f

    3. The attempt at a solution
    I got 0.393 m with the equation 2L = v/f where v is the speed of sound through air and f is 440 m/s (effective frequency). The answer was rather 0.786 m whifch is basically L = v/f (without the 2L). Isn't lambda = 2L?
    If so, where did it go?

    Take careful note of that wording.
