In Melde’s experiment in the transverse mode, the frequency of the tuning fork and the frequency of the waves in the strings are in the ratio

To reduce the frequency of a tuning fork –

Melde's experiment in perpendicular positon , the frequency of the string in equal to

In Melde's experiment , when the tuning fork is set in parallel position, the frequency of the string (n) and the frequency of the tuning fork (N) are related as

The prongs of the tuning fork are filled a little, the frequency of the tuning fork after filled

The prongs of the tuning fork are filled a little , the frequency of the tuning fork after filled

The prongs of the tuning fork are filed, then the frequency of the tuning fork after filing will be

31 tuning forks are arranged in series in increasing order of frequencies and the frequency of the last tuning fork is 3 times the frequency of the first. If each tuning fork produces 4 beats/second with the preceding one, the frequency of the last tuning fork is

In melde's experiment, when tension in the string is 100gm wt and the tuning fork vibrates transversely , then the number of loops are 4. then the string in turned through 90^@ , so that is vibrates longitudinally. What is the extra tension required to form one loop in the string ?
