QNEET-2018-Ph-884: NEET 2018 Physics - Class 12 NEET-2018-Ph-884 Solution: An EM wave is propagating in a medium with a velocity \( {v} =…
An EM wave is propagating in a medium with a velocity . 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 z direction +z direction -y direction -x direction
Multiple Choice Options
- A z direction
- B #NAME?
- C �y direction
- D �x direction
Step-by-Step Verified Solution
As we know,
E _ _ B _ = V _
_ E j ^ _ B _ = v i ^
[ As given Electric field vector is along +y axis and v _ = v i ^ ]
i ^ = j ^ _ k ^ so B _ = B k ^ .
_ Direction of magnetic field vector is along
+z direction.
