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

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

To reduce the frequency of a tuning fork –

A sonometer wire of length 65cm is in resonance with a tuning fork of frequency N. If the length of the wire is decreased by 1cm and it is vibrated with the same tuning fork, 8 beats/s are heard, then the frequency of the tuning fork will be

When prongs of a tuning fork are rubbed, its frequency decreases.

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

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

The frequency of tuning fork A is 2% more than the frequency of a standard tuning fork. The frequency of a tuning fork B is 3% less than the frequency of the same standard tuning fork. If 6 beat/s are heard when the tuning fork A and B are excited , then frequency of A will be

The frequency of tuning fork A is 2% more than the frequency of a standard tuning fork. The frequency of a tuning fork B is 3% less than the frequency of the same standard tuning fork. If 6 beat/s are heard when the tuning fork A and B are excited , then frequency of A will be
