Question

How are electromagnetic wave produced?​

Answer 1

$\huge\underline\frak{\fbox{AnSwEr :-}}$

According to Maxwell's electromagnetic theory, an accelerated charge radiates electromagnetic waves. For example, a time-varying current on a linear antenna generates a circulating and time- varying magnetic field, which through Faraday's law generates a circulating electric field, which through Ampère's law generates a magnetic field, and so on. The cross-linked electric and magnetic fields propagate away from the antenna

Answer 2

Answer:

Electromagnetic waves r produced by accelerated or oscillating charges nd do not need any medium for propagation. The source of energy of these waves r energy of oscillating charge particle.
