A tuning fork produces 8 beats per second with a tuning fork D of frequency `350 Hz`.When the prongs of fork C are loaded with wax, the number of beats heard is 10 per second. Find the original frequency of fork C.

A tuning fork C procues 8 beats per second with another tuning f+ork D of frequency 340 Hz . When the prongs of tuning fork C are filled a little, the number of beats produced per second decreases to 4 . Find the frequency of the tuning fork C before filing its prongs.

A stretched sonometer wire is in unison with a tuning fork.When the length is increased by 4 % , the number of beats heard per second is 6. Find the frequency of the fork.

A vibrating string of certain length l under a tension T resonates with a mode corresponding to the first overtone (third harmonic) of an air column of length 75cm inside a tube closed at one end. The string also generates 4 beats per second when excited along with a tuning fork of frequency n . Now when the tension of the string is slightly increased the number of beats reduces 2 per second. Assuming the velocity of sound in air to be 340 m//s , the frequency n of the tuning fork in Hz is

Two turning forks produce 4 beats per second when sounded together,The frequency of one of them is 200 Hz.When the other tunning fork is loaded with a little wax. The beats stop.The frequency of second funinf fork is

A resonance air column of length 20 cm resonates with a tuning fork of frequency 250 Hz . The speed of sound in air is

Wire having tension 225 N produces six beats per second when it is tuned with a fork. When tension changes to 256 N, it is tuned with the same fork, the number of beats remain unchanged. The frequency of the fork will be

A tuning fork gives 4 beats per second with a sonometer wire under tension of 26 N. If the tension on the wire is decreased to 24 N the number of beats remains the same before. What is the frequency of the tuning fork?

Two tuning forks A and B produce 8 beats per second when sounded together ,When B is slightly loaded with wax the beats are reduced to 4 per second .If the frequency of A is 512 Hz,the frequency of B is

Nine tuning forks are arranged in order of increasing frequency . Each tuning fork produces 4 beats per second when sounded with either of its neighbours. If the frequency of the 9th tuning fork is twice that of the first, what is the frequency of the first tuning fork ?

When a tuning fork A and B are sounded together,the number of beats heard are 4 per second.When tuning fork A is field,the number of beats heard per second with B is changed to 3.If the frequency of tuning fork B is 384 Hz,the original frequency of A is
