Q.
A transverse simple harmonic wave is travelling on a string. The equation of the wave :
Waves
Solution:
The equation of a simple harmonic wave is given as
$y=A \sin (\omega t-k x)$
This equation gives the displacement curve (shape of a string in which transverse wave is propagating) as well as it gives the displacement of a particle at position $x$ as a function of time $t$.
