Assignment:
Suppose a plane electromagnetic wave has a wavelength of 50 m and the electric field vibrates with an amplitude of 22 V/m. Calculate the frequency of the wave, the amplitude of B. Write an expression for B in a the form B=B0 cos(kx-ωt) with numerical values for B0, k, and ω.
Provide complete and step by step solution for the question and show calculations and use formulas.
