    The oscillating electric and magnetic vectors of an electromagnetic wave are oriented along 

  • Question 2
    1 / -0

    A parallel plate capacitor with plate are $$A$$ and seperation between the plates $$d,$$ is charged byb a constant current $$i,$$ consider a plane surface of area $$A/2$$ parallel to the plates and drawn symmetrically between the plates, the displacement current through this area, will be.

  • Question 3
    1 / -0

    If $$\vec{E}$$ and $$\vec{B}$$ are electric and magnetic field vectors of electromagnetic waves, then the propagation of electronic wave is along

  • Question 4
    1 / -0

    The figure here gives the electric field of an $$EM$$ wave at a certain poiunt and a certain instrant. the wave is transporting energy in the negative $$z$$ direction. what is tha direction of the magnetic field of the wave at that point and instant.
