Assertion (A): 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.
Reason (R): If a travelling wave sent along a particular string by oscillating its one end, it is the wave length of the wave that decreases.
Reason (R): If a travelling wave sent along a particular string by oscillating its one end, it is the wave length of the wave that decreases.
View answer and explanation
Correct option: D
Assertion is false but Reason is true
Assertion is false but Reason is true. The speed of a wave on a string depends on the tension and mass per unit length, not the frequency. The wavelength decreases when the frequency increases, keeping the speed constant.
