Measuring the Velocity of a Standing Wave

APPH12-ONEJHX

Which of the following procedures best describes how to measure the velocity of a standing wave down a string (attached at both ends)?

A

Use a force sensor or hanging mass to measure the force exerted on the string. This measurement is all that is needed to measure the wave velocity.

B

Measure the length of the string. Use a force sensor or hanging mass to measure the force exerted on the string. Measure the mass of the string. These measurements are all that is needed to measure the wave velocity.

C

Measure the length of the string. Measure the mass of the string. These measurements are all that is needed to measure the wave velocity.

D

Measure the mass of the string. This measurement is all that is needed to measure the wave velocity.
