Physics · JEE | Electromagnetic Waves
हिन्दीGiven below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R).\n Assertion (A): Stationary charges cannot be sources of electromagnetic waves.\n Reason (R): A stationary charge produces only a time-independent electric field and no magnetic field. \nIn the light of the above statements, choose the correct answer from the options given below:
View Answer & Solution
Correct answer · Option A
Both (A) and (R) are true and (R) is the correct explanation of (A).
Explanation
Stationary charges produce only electrostatic fields, which do not vary with time and thus cannot generate time-varying magnetic fields required for electromagnetic waves.
