Explain with the help of diagram how sound propagate through air.​

see below, but I can't add a diagram

Explanation:

When the source vibrates, it causes particles near it to vibrate back and forth vigorously. As these particles vibrate, they collide with the neighbouring particles , passing on the energy and making them vibrate vigorously. this forms a series of compressions and rarefactions . this process continues as a longitudinal wave until the vibrations reach our ear

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
