In a sound wave in air, the adjacent rarefactions and compressions are separated by a distance of 17cm. If the velocity of the sound wave is 340ms^-1. Determine the frequency

y'all are forgetting that they didn't specify whether it was an open pipe or closed they just stated in air

When should we use 2L

plz how did they get 3.4 * 10^2

Are we not supposed to een convert cm to m

So when do we use 4L

v=340 L=17cm f=?
convert 17cm to m = 17 =0.34
100
Bcos a wavelength is made up 1rarefaction and 1 compressions
wavelength= 2L =0.17 x 2 = 0.34

f= velocity
wavelength
= 340 = 1000
0.34

adjacent rarefactions and compressions mean the rarefactions and compressions are side by side each other
C-R-C-R
from one compression to the next rare faction is half wavelength

Myschool Paul, Kelly or Blessing please why do we use 2L as wavelength and not L?
