The generally equation for the mechanical wave is
The speed of the transverse wave is
The amplitude of the transverse wave is
The wavelength of the transverse wave is
At t= 0.150s , x = 1.51 m
The angular frequency of the wave is mathematically represented as
Substituting values
The propagation constant k is mathematically represented as
Substituting values
Substituting values into the equation for mechanical waves
