CONCEPT: Electromagnetic waves or EM waves: The waves that are formed as a result of vibrations between an electric field and a magnetic field and they are perpendicular to each other and to the direction of the wave is called an electromagnetic wave. The accelerating charged particle produces an electromagnetic (EM) wave. A charged particle oscillating about an equilibrium position is an accelerating charged particle. Electromagnetic waves do not require any matter to propagate from one place to another as it consists of photons. They can move in a vacuum. Properties of electromagnetic waves: Not have any charge or we can say that they are neutral. Propagate as a transverse wave. They move with the velocity the same as that of light i.e 3 × 108 m/s. It contains energy and they also contain momentum. They can travel in a vacuum also. EXPLANATION: From the above discussion, they can travel in a vacuum and they have electric and magnetic components that are mutually perpendicular. options 2 and 3 are correct.
