Homework Statement
The two strings in the figure are of equal length and are being driven at equal frequencies. The linear density of the left string is 2.4 g/m
Homework Equations
AND ATTEMPT AT SOLUTIONAssume that while the spring provides the same tension to both strings it also acts as a fixed
point for the end of each string so an integral number of half wavelengths fit in each string.
Visualize: Use a subscript L for the left string and R for the right string. We are given μL = 2.0 g/m. From the
assumption above we know (Ts left ) = (Ts right ) = Ts . We are also given frequency left = frequ. right = frequency Notice from the
diagram that λleft=L and λright=2/3L
From v =λ f and s v = T /μ eliminate v and solve for μ : μ = T/(λ/f)^2
I am stuck here and keep getting the wrong answer. Can someone please explicitly solve this for me (include even algebraic steps because I keep just getting 2/3 for my answer)
