Graphs of Sound WavePressure-Distance Graph (for all particles)Displacement-Distance Graph (for all particles)
Displacement-Time Graph (for individual particle)
Both C and R are at position of zero displacement.
Amplitude, A: maximum distance from the rest or central position, in either direction. Period, T: time taken for each particle to complete one oscillation. Prediction on Particle Movement (Optional)Remember that in longitudinal wave, particles always move towards compression region! So,
For particles lie on the wave from A to B, they will move to left; For particles lie on the wave from A to D, they will move to right. |
