Two tuning forks vibrate with the same amplitude but the frequency of the first is double the frequency of the second. Which fork produces more intense sound in air ?

The frequency of fork A is 3% more than the frequency of a standard fork where as the frequency of fork B is 3% less. The fork A and B produce 6 beats per second. The frequency of standard fork will be -

A sonometer wire is vibrating in resonance with a tuning fork. Keeping the tension applied same, the length of the wire is doubled. Under what conditions would the tuning fork still be is resonance with the wire?

Two sources A and B vibrate with the same amplitude. They produce sounds of frequencies 1kHz and 30kHz respectively. Which of the two waves will have larger power? (AS_1)

41 tuning forks are arranged such that every fork gives 5 beats with the next. The last fork has a frequency that is double of the first. The frequency of the first fork is :-

When tuning forks A and B are sounded together, 20 beats are produced in 8 second between them. (i.e. beat frequency is (20)/(8) =2.5 Hz). Now, when some wax is applied on one of these tuning forks, 32 beats are produced in 8 s. If frequency of that fork on which wax is not applied is 512 Hz then find frequency of another tuning fork, before and after applying wax.

A cylinder ABC consists of two chambers 1 and 2 which contains two different gases. The wall C is rigid but the walls A and B are thin diaphragms. A vibrating tuning fork approaches the wall A with velocity u = 30 m//s and air column in chamber 1 and 2 vibrates with minimum frequency such that there is node (displacement) at B and antinode (displacement) at A. Find : (i) the fundamental frequency of air column (ii) find the frequency of tuning fork. Assume velocity of sound in the first and second chamber be 1100 m/s and 300 m/s respectively. .

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

16 tuning forks are arranged in increasing order of frequency. Any two consecutive tuning forks when sounded together produce 8 beats per second. If the frequency of last tuning fork is twice that of first, the frequency of first tuning fork is :-

A tuning fork A, marked 512 Hz, produces 5 beats per second, where sounded with another unmarked tuning fork B. If B is loaded with wax the number of beats is again 5 per second. What is the frequency of the tuning fork B when not loaded ?

A metre - long tube open at one end, with a movalble piston at the other end, shows resonance with a fixed frequency source (a tunning fork of frequency 340 Hz)when the tube length is 25.5 cm or 79.3 cm. Estimate the speed of sound in air at the temperature of the experiment. The edge effects may be neglected.
