Two organ pipes, open at one end but closed at the other, are each 1.14 m long. One is now lengthened by 2.00 cm. Find the beat frequency that they produce when playing together in their fundamentals.

A string has a mass of 7.8g and a length of 1.55m. A second string has a mass of 4.4g and a length of 2.45m. One end of each string is melted to the other to form one long string. This combined string is stretched tight with a tension of 18.7N. How long would it take for a transverse disturbance introduced at one end of the string to reach the opposite end of the string?

A steel wire in a piano has a length of 0.520 m and a mass of 4.600 x 103 kg. To what tension must this wire be stretched so that the fundamental vibration corresponds to middle C (f. = 261.6 Hz on the chromatic musical scale)? Need Help? Read It

A string experiences several harmonic frequencies. Two successive frequencies are 325Hz and 390Hz. a) What is the fundamental frequency? b) What is the next harmonic higher than 195Hz? c) Which harmonic is this?

Two timpani (tunable drums) are played at the same time. One is correctly turned so that when it is struck, sound is produced that has a wavelength of 2.20m. If the speed of sound is 343m/s, what beat frequency is heard?

Standing wave are formed on a string of length 3.0 m.  For a wave speed of 20.0 m/s, determine the period of the fifth overtone.

A nylon rope of length 16m is under a tension of 1.5 × 104 N. The total mass of this rope is 2.1 kg. If a wave pulse starts at one end of this rope, find its speed. Calculate to one decimals?

A nylon rope of length 12m is under a tension of 1.7 × 104 N. The total mass of this rope is 2.4 kg. If a wave pulse starts at one end of this rope, find its speed. Calculate to one decimals?

Question 12 12. A string of length 0.58 m is producing a standing wave of period 7 second with 9 harmonics. The speed (m/s) of the wave of the string is:

An organ pipe has a length of 2.45m and is open at both ends. Determine the fundamental frequency and draw what the standing wave pattern for this frequency looks like.
