A smoked plate falls vertically under gravity. A tuning fork traces wave on it. It is found that the lengths of two conscutive grounps of 10 waves are 5.143 and 6.64 cm respectively. What is the frequecny of the fork ?

A smoked plate falls vertically under gravity and a tuning fork traaces waves on it. It was found from the trace that there 10 waves are spaced over 4.2 cm. Calculate the frequecny of the tuming fork.

A tuning fork produces 4 beats /sec, with a sonometer wire of length 40 cm. It is found that when the length is increased to 44 cm, by keeping other factors constant, again 4 beats/sec are produced. What is the frequency of the tuning fork ?

A tuning fork produces 4 beats//sec , with a sonometer wire of length 40 cm. It is found that when the length is increased to 44 cm, by keeping other factors constant, again 4 beat//sec are produced. What isthe frequency of the tuning fork?

Two unknown frequency tuning forks are used in resonance column apparatus. When only first tuning fork is excited the 1^(st) and 2^(nd) resonating lengths noted are 10 cm and 30 cm respectively. When only second tuning fork is excited 1^(st) and 2^(nd) resonating lengths noted are 30 cm and 90 cm respectively. The ratio of the frequency of the 1^(st) to 2^(nd) tuning fork is.

A length of 34 cm of a sonometer wire gives 5 beats per second with a tuning fork.It again gives 5 beats per second when the length of the wire is increased to35 cm. What is the frequency of fork?

A 75 cm long sonometer wire is in resonance with a tuning fork. If the length of the wire is decreased by 3 cm , it produces 6 beats per second with the tuning fork . What is the frequency of the tuning fork ?

Two tuning forks resonate with air columns of lengths 16 cm and 25 cm, respectively. If the lower frequency is 320 Hz then, ignoring end corrections, the frequency of the other fork is

A light pointer fixed to one prong of a tuning fork touches gently a smoked vertical plate. The fork is set vibrating and the plate is allowed to fall freely. Two complete oscillations are traced when the plate falls through 40cm. What is the frequency ( in Hz ) of the tuning fork ?
