Question

Statement-1 : When a travelling wave is sent along a particular string by oscillating one end, the speed of the wave will increase if we increase the frequency of oscillations.
Statement-2 : If a travelling wave sent along a particular string by oscillating its one end, it is the wavelength of the wave that decreases.

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

Velocity $=$ wavelength $\times$ frequency. Thus velocity increases when either of them increase.
