Question

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 the assertion and reason are true and reson is a true explanation of the assertion.
B. if both the assertion and reason are true but the reason is not the correct explanation of assertion.
C. If the assertion is true but reason is false.
D. If both the assertion and reason are false.

Answer 1

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