In Meldes experiment in the transverse mode, the frequency of the tuning fork and the frequency of the waves in the string are in the ratio:

A)  \[2:1\]                                 

B)  \[4:1\]

C)  \[1:1\]                                 

D)  \[1:2\]

Correct Answer: C

Solution :

In transverse arrangement the tuning fork is placed such that the vibration of the prongs is in direction perpendicular to the length of the string as shown in figure. As the tuning fork completes one vibration, the one vibration of wave on string is completed. Thus, in transverse mode, its frequency is the same as that of the fork. Hence, the required ratio is \[1:1\].
