An electromagnetic wave in a vacuum traveling in the +x direction generated by a variable source initially has a wavelength of 2.65 x 10^4 m and a maximum electric field Emax in the +y direction of 8.20×10^−3 V/m. What are the coefficients in the equation for the magnetic field component of the wave after the period increases by a factor of 1.90?
Bmax = ?
k = ?
w = ?
So far I have Bmax = 2.733 x 10^11 T, k = 1.102 x 10^8 1/m, w = 3.744 x 10^ 14 rad/s
I know at least one of those is wrong, but I don't know why.

Nevermind I got it.
