Question

Statement-1 : Two pulses are traveling along a uniform string in opposite directions. One of them is inverted pulse when compared with the other in shape. There is no point clamped between the pulses. Then they will have different speeds.
Statement-2 : In a uniform string under a given tension, wave speed of any pulse is same.

• 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

The correct option is D If statement-1 is false and statement-2 is true

A point being clamped is not a necessary condition for waves to have different speeds waves might have some velocity but may not have clamped point because of different frequencies of the waves.
Velocity $\propto$ is square root of tension.
