State four properties of electromagnetic waves?

The Four Properties Of Electromagnetic Waves Are As Follows -

1)Electromagnetic Waves Are Propagated By Oscillating Electric Field And Magnetic Field At Right Angles To Each Other.

  1. 2) Electromagnetic Waves Are Transverse Waves And Do Not Need A Medium To Propagate.
  2. 3) Electromagnetic Waves Can Be Polarized When Passed Through A Thin Film Called Polarizers.
  3. 4) Electromanetic Waves Shows Interference And Diffraction Patterns.

1- they do not require any material medium to propagate 2- they all travel with the same speed in vacuum/ air = 3 * 10^8 m/s 3- they are not deflected by electric and magnetic fields 4- they are transverse waves

1- these waves do not require any material medium for their propagtion. 2-these waves are neutral,so they do not deflectes by electric and magnetic field.

they are temporary magnets and remain magnetic till current flows through them
