A light pointer fixed to one prong of a tuning fork touches gnetly a smoked vertical plate. The fork is set vibrating and the plate is allowed to fall freely. 8 complete oscilllations are counted when the plate falls through 10cm.What is the frequency of the tuning fork?

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 ?

A light pointer fixed to one prong of a tuning fork touches a vertical plate. The fork is set vibrating at a frequency of 56 Hz and allowed to free fall. Calculate how many complete oscillation are couhnted when plate falls st 10 cm

A tuning fork when vibrating along with a sonometer produces 6 beats per second when the length of the wire is either 20 cm or 21 cm . Find the frequency of the tuning fork.

When one of the prong of a tuning fork is waxed a little then frequency of the fork will

When wax is attached to one of the prongs of a tuning fork, frequency of the fork will

A pointer attached to a vibrating fork presses a smoked cylinder lightly. The cylinder is suddenly rotated through one complete revolution in 0.75 seconds. The pointer traces 192 waves on the cylinder. Calculate 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 beats/sec are produced. What is the frequency of the tuning fork ?

When a little wax is put on the prongs of a tuning fork, then the frequency of vibration of a tuning fork will
