[QUOTE="nil1996, post: 4543354, member: 475181"] [h2]Homework Statement [/h2] In a standing wave on a string (a)In one time period all the particles are simultaneously at rest. (b)All the particles must be at their positive extremes simultaneously once in time period. (c)All the particles may be at their positive extremes simultaneously once in time period. (d)All the particles are never at rest simultaneously. [h2]Homework Equations[/h2] concepts of waves [h2]The Attempt at a Solution[/h2] (a) Yes it is[B] true[/B], at maximum positions all particles are at rest. (b)This is only true for fundamental frequency of the standing waves, but that is not mentioned . So it is [B]false[/B] (c)This is where i am confused. This condition can only happen in fundamental frequency.But the particles are twice at their positive extremes.So i am not sure about it. One of books say that this is false while other says this is true. (d)False Please help me on the [B]c[/B] option. [/QUOTE]
