What is electromagnetic wave?

Answer 1

Electromagnetic waves are transverse (unpolarized or polarized) or circularly polarized waves that have some electrical properties and some magnetic properties.

An electromagnetic wave consists of changing electric and magnetic fields. The repeated cyclic transfer of energy from the electric field (weakening it) to the magnetic field (strengthening it) until the electric field is gone, then from the magnetic field (weakening it) to the electric field (strengthening it) until the magnetic field is gone every cycle is the process by which electromagnetic waves propagate without requiring a medium (and is described in Maxwell's Equations).
