EXECUTE the solution as follows Constants Learning Goal: Part C To practice Problem-Solving Strategy 32.1 Electromagnetic Waves. What are the coefficients in the equation for the magnetic field component of the wave after the period increases by a factor of 2.70? An electromagnetic wave in a vacuum traveling in the +x direction generated by a variable source initially has a wavelength A of 235 Arm and a maximum electric field Emax in the ty direction of 3.60x10-3 V/m. If the period of the wave is then increased by a factor of 2.70, what is the equation of the resulting magnetic field component of the wave? Enter the maximum magnetic field, wavenumber, and angular frequency in teslas, inverse meters, and radians per second separated by commas. T, 1/m,rad/s Submit EVALUATE your answerExplanation / Answer
Bm = Em/c = 3.60x10^-3 / 3 x 10^8 = 1.2 x 10^-11 Vs/m^2
k = 2pi/lambda' = 2pi/2.70x 235x10^-6 = 9902.5 m^-1
w = ck = 3x10^8 x 9902.5 = 2.97 x 10^12 s^-1
