  • Option 2)

    The energy in electromagnetic wave is divided equally between electric and magnetic vectors

  • Option 3)

Electromagnetic Wave -

Combination of mutually perpendicular electric and magnetic field is referred to as Electromagnetic Wave.

-

 

 EM wave have both electric and magnetic field mutually perpendicular and both perpendicular to direction of propagation.

energy is equally divide between electric and magnetic field. 

Both electric and magnetic field are in phase


They do not require any medium to propagate (e.g. vacuum)


Option 1)

Both electric and magnetic field vectors attain the maxima and minima at the same place and same time

This solution is incorrect 

Option 2)

The energy in electromagnetic wave is divided equally between electric and magnetic vectors

This solution is incorrect 

Option 3)

Both electric and magnetic field vectors are parallel to each and perpendicular to the direction to propagation of wave

This solution is correct 

Option 4)

These waves do not require any material medium for propagation

This solution is incorrect
