. However I am going to solve it for both signs, if there is a minus sign then it is traveling in +y direction, if there is a plus sign then it is traveling in -y.![\omega = 2\pi f = 1.2501013=f =0.19896 [Hz]](/tpl/images/0377/0513/8e8ed.png)
![\lambda = \frac{c}{f} = \frac{3*10^8}{0.19896} = 1.5*10^9 [m]](/tpl/images/0377/0513/571cd.png)
