Answer:
Electromagnetic waves are produced when something vibrates—an electric charge that moves back and forth. When an electric charge vibrates, the electric field around it changes. Because the electric charge is in motion, it also has a magnetic field around it. This magnetic field also changes as the charge vibrates

According to the law of electromagnetism, a current ‘carrying conductor’ or an electric charge moves, a magnetic field is produced. Since the electric charge vibrates it has a constant to and fro motion.
Explanation:
- This produces a rise and a fall of the magnetic field. In the electromagnetic field produces a wave like motion.
- This results in the formation of electromagnetic wave when an electric charge vibrates about its mean position.
- The ‘wavelength’ depends on the ‘frequency of the vibration’.
