Question

As we go up in a harmonic series, what happens to the wavelength of the waves producing a harmonic? A. increases B. decreases C. remains the same

Answer 1

correct answer is ................. decreases................... b

because harmonics increases frequency of harmonics also increases

from v = f * lamda

at constant velocity frequency increaes wavelength decreases

and in open pipes wavelength = lamda = 2L / n                 n = harmonic number

in closed pipes also wavelength = lamda = 4L / n

so from the above equations also harmonics value n increases lamda decreases
