Wave Mechanics Question 781
Question: Assertion : Particle velocity and wave velocity both are independent of time. Reason : For the propagation of wave motion, the medium must have the properties of elasticity and inertia.
Options:
A) If both assertion and reason are true and the reason is the correct explanation of the assertion.
B) If both assertion and reason are true but reason is not the correct explanation of the assertion.
C) If assertion is true but reason is false.
D) If the assertion and reason are both false.
E) If assertion is false but reason is true.
Show Answer
Answer:
Correct Answer: E
Solution:
The velocity of every oscillating particle of the medium is different at its different positions in one oscillation but the velocity of wave motion is always constant i.e., particle velocity varies with respect to time, while the wave velocity is independent of time. Also for wave propagation medium must have the properties of elasticity and inertia.
