Electromagnetic waves are generated by

Options

  1. Aa moving charge
  2. Buncharged particles
  3. Ca stationary charge
  4. Dan accelerating charge

Correct answer

D. an accelerating charge

Step-by-step solution

A stationary charge produces only an electric field in the surrounding space. A charge moving with a uniform velocity produces both electric and magnetic fields but does not radiate energy. An accelerating charge produces oscillating electric and magnetic fields which propagate through space in the form of electromagnetic waves. Therefore, electromagnetic waves are generated by an accelerating charge.
