  • When an electromagnetic wave travels fromone medium to another with a different speed of propagation, thefrequency of the wave remains the same. Its wavelength, however,changes. (a) If the wave speed decreases, does the wavelength increase or decrease? Explain. (b) Consider a case where the wave speeddecreases from c to 34c. By what factor does the wavelength change?
    We have a plane electromagnetic wave traveling in the +z direction. As you may recall, plane waves have electric and magnetic fields that vary like either sine or cosine, with an argument of (kz−ωt). Our goal here will be to write down the equations describing the electric and magnetic fields in this particular wave, and then use those equations to calculate a few quantities.Let's suppose that at z=0 and t=0, the magnetic field has its maximum value B0 and points in the −y direction. Use that information to decide whether your B -field should vary like sine or like cosine, and write a symbolic vector expression for B . Then write a symbolic vector expression for the E -field that would be in this wave. The definition of the Poynting vector will let you figure the direction of the E -field.   A) The frequency of this wave is f=3.060e+06 Hz. What is the scalar value of the magnetic field at t=1.29e−07 s? You can still assume that z=0, and that B0 = .0056 T .    For m answer I got .0059 T…
