Ordinary light oscillates in_____plane passing through the line of propagation.

Answer»

infinite
two
four
three

Solution :If we were to view a beam of ordinary light from one end and if we could actually see the PLANES in which the ELECTRICAL oscillations were OCCURRING, we could find that oscillations of the electric field were occurring in all possible planes perpendicular to the direction of propagation. The same WOULD be true of the MAGNETIC field.
