A little Physics help anyone?

Question

A standing wave function for n=1 is given as y(x,t)= 2sin( x(π/4) ) sin(π t).
Here, k= π/4, w (or omega) = π, lamda (or wavelength)=8 m, L=4 m, T=2 sec, and f=1/2 Hz.

Now, for n=3, regarding finding the new y(x,t) equation, how do you solve for the w (omega) of the new equation?

Answer 1

I suppose you'd just cut and paste my answer, like you did the question. Read the book.
