B~ (x, y, z, t) = B0 sin (x + y)k√2+ ωtˆk
where k is the wave number and ˆi, ˆj and ˆk are the Cartesian unit vectors in x, yand z directions, respectively.The electric field E~ (x, y, z, t) corresponding to the above wave is given by
An electromagnetic plane wave, that is propagating in the x-direction at a speed of 3.00 x108 m/s, has a peak electric field strength of 4,200 N/C and a wavelength of 900 nm. Which of the following functions represents the correct behavior for the magnetic field?
a.
B(x, t) = (21 µT)sin[(9.00 x 10-7 m-1)x – (2.09 x 1015 rad/s)t]
b.
