प्रश्न
A plane electromagnetic wave propagating along x direction can have the following pairs of E and B.
- Ex, By.
- Ey, Bz.
- Bx, Ey.
- Ex, By.
विकल्प
b and c
a and c
b and d
c and d
उत्तर
b and d
Explanation:
As the EM wave is plane polarized and its propagation is in +X direction. So direction of `vecE` and `vecB` will be in either Y and Z direction or Z and Y direction.
Here in the question, electromagnetic wave is propagating along the x-direction. So, electro and magnetic field vectors should have either y-direction or 2-direction.
