MCQ

An electromagnetic wave is propagating along $Y-$axis. Then.

A
oscillating electric field is along $X-$axis and oscillating magnetic field is along $Y-$axis
✓
oscillating electric field is along $Z-$axis and oscillating magnetic field is along $X-$axis
C
both oscillating electric and magnetic fields are along $Y-$axis, but phase difference between them is $90^{\circ}$
D
both oscillating electric and magnetic fields are mutually perpendicular in arbitrary direction

✓

Answer

Correct option: B.

oscillating electric field is along $Z-$axis and oscillating magnetic field is along $X-$axis

electromagnetic radiation consists of electromagnetic waves, which are synchronized oscillations of electric and magnetic fields that propagate at the speed of light through a vaccum. The oscillations of the two fields are perpendicular to each other and perpendicular to the direction of energy and wave propagation, forming a transverse wave. so if propogation is along $Y-$direction ,Electric field will be along $X$ or $Z$, if it is along $Z -$direction than Magnetic field has to be in $X -$direction.
