Q10 of 97 Page 323

In a stationary wave,

If at an instant red sine wave is showing than after sometime blue sine wave will be shown. It is clear from the diagram that the alternate antinodes are in the same phase.


In the whole process only nodes are static points. So, the minimum distance where all the particles vibrate, is the region in between the nodes.

Mark out the correct options.

 1

A wave pulse passing on a string with a speed of 40 cm s−1 in the negative x-direction has its maximum at x = 0 at t = 0. Where will this maximum be located at t = 5 s?

 2
