Hint: Electromagnetic waves are produced when an electric field comes into contact with a magnetic field. It can also be said that the composition of oscillating electric and magnetic fields consists of electromagnetic waves.

Complete answer:
1.If you ever went swimming in the ocean, the waves are familiar to you already. In a specific physical medium or field, waves are simply disturbances, resulting in a vibration or oscillation. 2.The ocean swells of a wave, and the subsequent dip that follows, is simply a water vibration or oscillation at the surface of the ocean.
3.There are similar electromagnetic waves, but they are also different in that they actually consist of 222 waves oscillating perpendicular to each other. One of the waves is a magnetic field which oscillates.
4. Electric fields are generated by time-varying magnetic fields and vice versa. A set of equations known as Maxwell's equations describe the behavior of time dependent electromagnetic waves.
5. The quantity of power passing through any spherical surface drawn around the source is the same due to energy conservation.
6.The waves travel at a constant speed of $3 \times 10^{8} \mathrm{~ms}^{-1}$ in the vacuum. In a vacuum or without any medium, electromagnetic waves can transmit energy. Within communication technology, electromagnetic waves play an important role

Note:
A sinusoidal graph demonstrates electromagnetic waves. It consists of electric and magnetic time-varying fields which are perpendicular to each other and are also perpendicular to the wave propagation direction. Electromagnetic waves, in nature, are transverse. The wave's highest point is known as a crest, while a trough is known as the lowest point.
