The same thread (2 m weighs 1 g) is used in a longitudinal Melde set-up with a 150 Hz vibrator and a total load of 20 g. Find the length that vibrates in 3 loops.

Answer:

0.40

Solution:

$T = 0.02 \times 9.8 = 0.196$ N, $v = 0.196/5 \times 1 0^{- 4} = 19.8$ m/s, string frequency 75 Hz, $λ = 0.264$ m, $L = 3 λ /2 = 0.396$ m.
