Q. Which of the following produces Electromagnetic waves?
✅ Correct Answer: (C)
accelerated charges
Explanation: Neither stationary charges nor charges in uniform motion (steady currents) can be sources of electromagnetic waves. The former produces only electrostatic fields, while the latter produces magnetic fields that, however, do not vary with time. As per Maxwell’s theory, accelerated charges radiate electromagnetic waves.
