The su$ o' two counter,propaatin wa&es o' e-ual a$plitu"e an" 're-uency creates a stan"in wa&e. The &iration o' the strin is then a co$posite $otion resultin 'ro$ the co$ine" e''ect o' the two oppositely "irecte" wa&es. !' the proper relationship e#ists etween the 're-uency% the lenth an" the tension% a stan"in wa&e is pro"uce" an" when the con"itions are such as to $a*e the a$plitu"e o' the stan"in wa&e a $a#i$u$% the syste$ is sai" to e in resonance.

2. Discuss result
0ro$ the e-uation w=4u'2L2% it shows that the weiht o' the loa"%w % is "irectly proportional to the "istance etween two no"es alon a stan"in wa&es%L.

4. Application A lare nu$er o' $usical instru$ents wor* on the principle o' resonance o' stan"in wa&es in strins that are 'i#e" etween two 'i#e" en"s. #a$ples o' these are the uitar% &iolin% u*ulele%piano% an" $any other instru$ents. 7esonance o' stan"in wa&es also play an i$portant role in the "esin o' cales use" an" the sa'ety $echanis$s incorporate" into% 'or instance% suspension ri"es% as such resonance can result in stan"in wa&es with &iration lare enouh to cause the collapse o' the ri"e% as ha" happene" "urin one stor$y ale in 184 when the /arrows 9ri"e in :+A collapse" as it allope" un"er resonance "ue to the stron win"s% an" eca$e *nown as the ;allopin ;ertie. 5. thers The 'ollowin $o"i'ications to the e#peri$ents is sueste" to i$pro&e the results 'urther 0irst% a &iration enerator that coul" enerate clearer an" stroner wa&es is reco$$en"e" to pro"uce clear no"es an" antino"es.
The $easurin ruler can also e hel" up usin a set o' retort stan"s so that rea"ins can e ta*en in a stale con"ition. Another suestion is to 'i# the lenth etween the two no"es an" &ary the 're-uency as the tension &aries% as the &ariation in the 're-uency is $ore accurately "eter$ine" than the $easure$ent o' the lenth etween the no"es.
