Longitudinal progressive wave

Questions

( Note : Particles are represented as thin lines for better visualization )

1. The wave is propagating toward right hand side. Are the particles oscillating along the same direction?

2. Are the particles executing SHM?

3. Are all the particles moving in phase?

4. Are any two particles moving in phase?

5. Is velocity of particles constant?

6. Is velocity of wave constant?

7. For a fixed velocity of the wave, what happens to wavelength when frequency is increased?

8. For a fixed frequency, what happens to wavelength when wave moves slower?

9. For a fixed frequency and velocity of wave, what happens to wavelength when amplitude of wave is increased?

10. To decrease the wavelength by half, for a fixed velocity of wave, what should be the increase/decrease in frequency?

11. Is displacement plot same as pressure plot?

Note :

Questions given above may be visualized and solved using the simulations, obtaining a mathematical solution is to be always treated as the final answer.

Such a mathematical solution implies that you are able to understand and apply the concept.
