Define electromagnetic radiation. the complete range of electromagnetic waves placed in order of increasing frequency is called Electromagnetic Spectrum.

a wave that consists of vibrating electric and magnetic fields

the transfer of energy by waves traveling through matter or across empty space.

Great amounts of electromagnetic energy from our sun and other bodies in space travel through space. which is a logical conclusion about these electromagnetic waves? their energy must be very their frequency must be very low these waves can travel without a medium they only travel through a vacuum of space
