A closed organ pipe of radius r_(1) and an open organ pipe of radius r_(2) and having same length 'L' resonate when excited with a given tuning fork. Closed organ-pipe resonates in its fundamental mode where as open organ pipe resonates in its first overtone, then :-

Two closed organ pipes of length 100 cm and 101 cm produce 16 beats in 20 sec. When each pipe is sounded in its fundamental mode calculate the velocity of sound in m/s.

A wave stretched between two rigid supports vibrate in its fundamental mode with a frequency of 45 Hz. The mass of wire is 3.5 xx 10^(-2) kg and its linear mass density is 4.0 xx 10^(-2) kg m^(-1) . What is (a) the speed of transverse wave on the string, and (b) the tension in the string?

A string of mass per unit length mu is clamped at both ends such that one end of the string is at x = 0 and the other is at x =l . When string vibrates in fundamental mode, amplitude of the midpoint O of the string is a, tension in a, tension in the string is T and amplitude of vibration is A. Find the total oscillation energy stored in the string.

In the experiment for the determination of the speed of sound in air using the resonance column method, the length of the air column that resonates in the fundamental mode, with a tuning fork is 0.1m . When this length is changed to 0.35m , the same tuning fork resonates with the first overtone. Calculate the end correction.

For a certain organ pipe, three successive resonance frequencies are observer at 425 , 595 and 765 H_(Z) respectively. Taking the speed of sound in air to be 340 m//s , (a) explain whether the pipe is closed at one or open at boyh ends. (b) determine the fundamental frequency and length of the pipe.

When two organ pipes with fundamental frequencies n_(1) and n_(2) are connected in series, what will be the resultant fundamental frequency?

An open organ pipe of length 1m contains a gas whose density is twice the density of the atmosphere at STP. Find the difference between its fundamental and second harmonic frequencies if the speed of sound in atmosphere is 300m/s.

The second overtone of an open organ pipe has the same frequency as the first overtone of a closed pipe L meter long. The length of the open pipe will be

A string 25cm long and having a mass of 2.5 gm is under tension. A pipe closed at one end is 40cm long. When the string is set vibrating in its first overtone and the air in the pipe in its fundamental frequency, 8 beats per second are heard. It is observed that decreasing the tension in the string decreases beat frequency. If the speed of sound in air is 320m//s , find the tension in the string.
