An EM wave is propagating in a medium with a velocity V → = V   i ^ . The instantaneous oscillating electric field of this em wave is along + y axis. Then the direction of oscillating magnetic field of the EM wave will be along

Options

  1. A- y direction
  2. B+ z direction
  3. C- z direction
  4. D- x direction

Correct answer

B. + z direction

Step-by-step solution

V ^ = E ^ × B ^ , i ^ = j ^ × k ^ ∴     B ^ = k ^ , + z direction
