Assertion : It is not possible to have interference between the waves produced byu two violins. Reason : For interferene of two waves the phase differnce between the wave must remain constant.A. If both assertion and reason are true and reason is the correct expleanation of assertion.B. If both assertion and reason are true and reason is not the correct expleanation of assertion.C. If assertion is true but reason is false.D. If assertion and reason both are false.

Answer» Correct Answer - A
Since the initial phase difference between the two waves coming from different violins changes, therefore, the waves produced by two different violins does not interfere because two waves interfere only when the phase difference between them remain constant throughout.
