In transmission of light waves, the angle between plane of oscillation and plane of polarisation is. A) 0° B) 90° C) 45° D) 80° |

Answer» The correct option is (B) 90° As we know that plane polarized light is defined as the an electromagnetic wave in which electric field vector and magnetic field vector oscillates perpendicular to each other. Also the plane of oscillation of field is perpendicular to the propagation of the light So here we can say that the light wave will propagate in such a way that transmission of light wave is always at 90 degree with the plane of polarization of the light. So the angle must be 90 degree. |
