An electromagnetic wave in a vacuum traveling in the +x direction generated by a variable source initially has a wavelength λ of 255 μm and a maximum electric field Emax in the +y direction of 2.20×10−3 V/m . The period of the wave is then increased by a factor of 1.70. What are the coefficients in the equation for the magnetic field component of the wave after the period increases by a factor of 1.70? Enter the maximum magnetic field, wavenumber, and angular frequency in teslas, inverse meters, and radians per second separated by commas. (Bmax, k,ω)
