Equations

Question 1

Equations for a String Harmonic

Answer 1

λ=2L/n
v=λf=Root Ft/μ
μ=m/l
λ=v/f
f=v/2L=nv/2L=n(Root Ft/μ)/2L

Question 2

Equations for open end resonator

Answer 2

λ=2L/n
f=nv/2L

Question 3

speed of sound

Answer 3

v=331.5+.6(T)

Question 4

equations for close-end resonator

Answer 4

λ=4L/n
f=nv/4L
1st harmonic: λ=4L/1
3rd harmonic: λ=4L/3
5th harmonic: λ=4L/5

Question 5
