12th Class Physics EM Waves Question Bank Assertion And Reason (MCQs) - Electromagnetic Waves

  • question_answer
    Assertion (A):  Dipole oscillation produce electromagnetic waves.
    Reason (R):  Accelerated charge produce electromagnetic waves.

    A) Both A and R are true and R is the correct explanation of A

    B) Both A and R are true but R is NOT the correct explanation of A

    C) A is true but R is false

    D) A is false and R is true

    Correct Answer: A

    Solution :

    Option [a] is correct. Explanation: A source of electromagnetic waves is accelerating charge, since accelerated charge produces both electric and magnetic field,  Again according to Maxwells' classical theory, dipole oscillation produces electromagnetic wave, since charges are accelerated. So, assertion and reason both are true and the reason explains the assertion.
