Gyrating Electron as EM Wave Source – Rankers Physics

Properties of EM Waves: Practice Problem & Solution

**Assertion (A):** The gyrating electron can be a source of EMW. **Reason (R):** The electron in circular motion is accelerated motion.  
Both (A) &(R) are true and the (R) is the correct explanation of the (A)
Both (A) &(R) are true but the (R) is not the correct explanation of the (A)
(A) is true but (R) is false
Both (A) and (R) are false

Short Solution (Best for NEET):

To solve this problem, we apply the core principles of Properties of EM Waves. Understanding the underlying formula is key to arriving at the correct answer below:

A gyrating electron undergoes circular motion, which is accelerated motion. Accelerated charges are sources of electromagnetic waves. Therefore, Assertion and Reason are true, and R correctly explains A.
