for 15 a) (question in attachment)
using given 0.54m i calculated L1
also after rearranging L1=λ/2 i got wavelength which is 1.08m
L2 = λ
and since the distance between all the resonant lengths is always the same, i just added 0.54 to length 2 to figure out length 3
which is L3=1.62m
my question is i can't seem to be able to find a formula for open ended column resonant frequencies for resonant length 3should i just use the universal wave equation? v=fλ
and re arrange and use f=v/λ
or is there a different equation for finding frequency of 3rd resonant length in open air columns?
how do i find the frequency for third resonant length?
