InterviewSolution

1.	The magnetic field intensity vector of a plane wave is given by (, , , ) = 10 sin (5000 + 0.004 + 30 ), where denotes unit vector in direction the wave is propagating with a phase velocity.
Answer» (x, y, z, t) = 10 sin (5000t + 0.004x + 30) Wave is propagating in - ve direction, hence v = - 1.25 x 107 m/sec.
