Title: ENERGY TRANSFER BY TENSION ON A STRING Post by: deepika.physicslover on February 15, 2009, 05:25:00 pm TRANSVERSE WAVE ON A STRING
Hi!! i have a doubt !!if any one can ans 2 dat den i will b grateful 2 him/her. here itz: when dere is a transverse wave travelling on a string we say dat da energy is transferred by da tension 4m left 2 da right.(dis is obvious as tension is continuously doing work) but while calculating da vel of da wave on a string we generally resolve tension(vich is tangential)into horizontal n vertical component n itz horizontal component gets cancelled n da resultant is in vertical direction so how come da tension is transferring energy along horizontal direction? i hope dat u got my doubt if not pleez let me know dat.

Title: Re: ENERGY TRANSFER BY TENSION ON A STRING Post by: deepika.physicslover on February 15, 2009, 08:59:31 pm my querry is just that which force is responsible for energy transfer across string ?
obviously it should b tension but as i said while calculating vel of a wave using newtonian mechanics we consider net force on that element n to do that we resolve the two tensions into horizontal n vertical component........ the tensions in horizontal (opposite direction)cancel each other n therefore the net is in the vertical direction............i donno if u got my doubt .......
