Question #ce1a2
1 Answer
String will not form loops.
Explanation:
If we observe the formation of stationary wave forms of different frequencires or wave lentgths in the streched strings as shown in the given figure,we see that to produce a stationary wave the antinode is first created by plucking the string in such a way that intgral number of loops are formed in the whole length(l)of the streched string.
Now length of one loop is equal to half of wave length
So
#l=(nlambda)/2,"where "n =1,2,3.....#
Again the plucking of string should be done at a distance
So
If
then
So to creat stationary wave
