Explanation:
Detailed explanation-1: -Overview. Electromagnetic waves are waves that consist of vibrating electric and magnetic fields. Like other waves, electromagnetic waves transfer energy from one place to another.
Detailed explanation-2: -A vibration is a wiggle in time. A wave is a wiggle in both space and time. A wave extends from one place to another. Waves are propagations of vibrations throughout space.
Detailed explanation-3: -In physics a wave is a disturbance or oscillation that travels through space accompanied by a transfer of energy, and may be propagated with little or no net motion of the medium involved. In this section we will consider mechanical waves, in which the particles in a material are oscillating.
