A string vibrates in its fundamental mode with a frequency of 200 Hz. The string is 0.64 m long and has a mass of 1.61 g. With what tension must the string be stretched?

v = (T/mu)^0.5
where v is the speed, T is the tension, and mu is the linear density
v = lamda*f ; lambda = 2*L for the fundamental mode, where f is the frequency, and lambda is the wavelength
f = (1/(2*L))*(T/mu)^0.5
1.61 g = 0.00161 kg
mu = 0.00161/0.64
200 = (1/(2*0.64))*(T/mu)^0.5
Plug in mu; use algebra to solve for T
