Question

In a string, longitudinal wave

• A. can be produced
• B. cannot be produced.
• C. May or may not be produced, depending on nature of fluid
• D. May or may not be produced, depending on nature of cross section of pipe

Answer 1

The correct option is A can be produced

We know that longitudanal waves require vibration of particles in direction of wave motion. These waves can be produced on a spring. Now, if the string is elastic, such waves can be produced as particles can vibrate along the length of the string.
