The minimum height of water column required for resonance to be first heard( Velocity of sound 340 ms-1) is. The frequency of a tuning fork is 384 Hz and velocity of sound in air is 352 ms. A tuning fork of frequency 340 Hz is excited and held above a cylindrical tube of length 120 cm. While we calculate the beat frequency, we subtract the smaller frequency from the bigger one so that the beat frequency remains positive. How many vibrations will a tuning fork of frequency 280 Hz complete during the time sound travels in the air by 20 m Take the speed of sound in air as 340 m/s. The frequency of the beats produced is given by, $$ on filing. Solution The correct option is A 45 cm We have v f. The beats produced per second refer to the difference between the frequencies of the two tuning forks. a tuning fork A of frequency 256 Hz and a tuning fork B are stuck. If the leng asked in Physics by Subodhsharma ( 86. ![]() Here, it is mentioned that the beats produced per second decreases when tuning fork C is filed. frequency f 2f0, f0 being threshold frequency, then the electrons are emitted with. In resonance tube experiment, first resonance occurs for the length of air - column equal to 25 cm with a tuning fork of frequency 340 Hz. These waves are used in the scientific field, it is used to study human heart rates, to take sonograms, navigation of directions, imaging things, uniform sample mixing, communication, testing of samples, etc.Hint:When the prongs of a tuning fork are filed, the frequency of that tuning fork will increase. A tuning fork of frequency 340 Hz is vibrated just above a cylindrical tube of length 120 cm.The velocity of sound in air is 344 m s 1. ![]() Since it is above the human hearing range, it is inaudible to humans. The frequency of a tuning fork is 256 H z.
