Question:
A transverse wave described by
$y=(0.02 m) \sin \left[\left(1.0 \mathrm{~m}^{-1}\right) x+\left(30^{s^{-1}}\right) t\right]$
Propagates on a stretched string having a linear mass density of $1.2 \times 10 \mathrm{~m}^{-4} \mathrm{~kg} /$ $\mathrm{kg} / \mathrm{m}$. Find the tension in the string.
Solution:
