Question

Statement-1 : When two wave pulses, identical in shape but one inverted with respect to other, approach each other, at some instant the displacement of all the particles will be zero.
Statement-2 : When two wave pulses identical in shape, one inverted with respect to the other, approach each other, at some instant the velocities of the particles will be zero.

• A. If both the statements are true and statement-2 is the correct explanation of statement-1
• B. If both the statements are true but statement-2 is not the correct explanation of statement-1
• C. If statement-1 is true and statement-2 is false
• D. If statement-1 is false and statement-2 is true

Answer 1

Answer: (C)

If statement-1 is true and statement-2 is false

When two wave pulses, identical in shape are inverted with respect to other then as time passes a point reaches when all the points will be zero because the two waves extinguish each other. At this point the velocities are not zero only displacements are zero.
