Explain the graphical representation of a sound wave in about 40-50 words
Answers
Answer:
Displacement-time graph is for an individual particle in the vibrating medium. It shows the displacement of a particle from the rest position at a particular time.
Compression, C: highest pressure of sound wave.
Rarefaction, R: lowest pressure of sound wave.
Amplitude, A: the maximum pressure change from surrounding pressure in either direction.
Wavelength: the distance between two consecutive C or R or any two points.
C and R are at position of zero displacement, when are at rest position.
Note:
The displacement-time graph is drawn for an instant of time. It changes at every instant of time. The direction of motion of sound wave can be determined by drawing displacement-time graphs at different instances of time.
