Homework Help: Physics

Posted by Faith on Monday, November 18, 2013 at 11:52pm.

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 8.2010^−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.
