Questions
The magnetic field in a plane electromagnetic wave is given by Write an expression for the electric field.
detailed solution
Correct option is A
E0=CB0=3×108×4×10−7=120 V/m Both electric and magnetic fields are in same phase. Wave is travelling in -x direction , Magnetic field is in y direction. So, electric field has to be along z direction.Similar Questions
