    properties of electromagnetic waves are as follows

    1. travels at the speed of light

    All electromagnetic waves can travel at speed of light through vacuum or air.

    2. made of magnetic fields

    All electromagnetic waves has magnetic field that oscillates perpendicular to the direction of wave

    3. made of electrical fields

    All electromagnetic waves has electric field that oscillates perpendicular to the direction of wave

    4. radiates from a source

    these electromagnetic waves are radiated from source in all directions normally outwards
