The magnetic of poynting vector and electric field vector are respectively `S` and `E`, then

The direction of poynting vector represents

The direction of poynting vector represents

The expression for electric field in vector form is

Is electric field scalar or vector ? Why ?

In an electromagnetic wave the electric field vector and magnetic field vector are given as vecE=E_(0)hati and vecB=B_(0)hatk respectively. The direction of propagation of electromagnetic wave is along:

Is magnetic field a scalar or a vector?

The phase and orientation of the magnetic vector associated with electromagnetic oscillations differ respectively from those of the corresponding electric vector by
