A horizontal stretched string, fixed at two ends, is vibrating in its $3 9^{th}$ overtone according to the equation, $y (x, t) = (0.01 m) sin [(62.8 m^{- 1}) x] cos [(628 s^{- 1}) t]$ .

Assuming π = 3.14, what is the length of string (in m)?

Answer:

Solution:

$k = \frac{2 π}{λ} = 62.8 λ = 0.1 m ℓ = 40 \frac{λ}{2} = 2 m$
