Answer:
Frequency of the wave will be 31.84 Hz
Explanation:
We have given the equation [tex]y=0.02sin(30x-200t)[/tex]-----eqn 1
The standard equation of sine wave is given by [tex]y=Asin(kx-\omega t)[/tex]----eqn 2
On comparing eqn 1 and eqn 2
[tex]\omega =200[/tex]
Angular frequency [tex]\omega[/tex] is given by [tex]\omega =2\pi f[/tex]
So [tex]200=2\times 3.14\times f[/tex]
[tex]f=31.84Hz[/tex]
