What is the effect when a system is driven in resonance? Is a particular frequency required? Explain. Would you expect to find a node or an antinode at the end of a plucked guitar string? Explain.

Two wires are welded together end to end. The wires are made of the same material, but the diameter of one is twice that of the other. They are subjected to a tension T. The thin wire has a length L and a linear mass density μ. The combined wire is fixed at both ends and vibrated in such a way that two antinodes are present, with the node between them being right at the weld. a. What is the frequency of vibration? b. What is the length of the thick wire?

World-renowned bluegrass musician, Frog Newton, has invited you to join his band. It is apparent that he is only looking for eye-candy on the stage, because you are only asked to play one note, the G# at a frequency of 415 Hz. You make your own instrument using a string that is 0.7 meters long and has a mass of 4 grams. Now you need to calculate the necessary tension on the string, And you will be ready to jam!   What is the wavelength of the first harmonic (also called the fundamental frequency) of standing wave created by the vibrating string m At what speed would a wave propagate on this string? m/s What is the linear density of the string? kg/m What is the tension needed to produce the G# note? N

A.) The frequency of a vibrating bar is inversely proportional to the SQUARE of its length: f = constant/L2. I have two identical bars, except that one has a length of 36.8 cm and the other a length of 24.2 cm. What is the ratio of the vibrational frequency of the shorter bar to the longer bar? B.)A 0.8 meter length of string in mode number 2 vibrates with a frequency of 385 Hz. What is the velocity of the wave on the string

World-renowned bluegrass musician, Frog Newton, has invited you to join his band. It is apparent that he is only looking for eye-candy on the stage, because you are only asked to play one note, the C at a frequency of 525 Hz. You make your own instrument using a string that is 0.5 meters long and has a mass of 2 grams. Now you need to calculate the necessary tension on the string, And you will be ready to jam! What is the wavelength of the first harmonic (also called the fundamental frequency) of standing wave created by the vibrating string m Submit Answer Tries 0/2 At what speed would a wave propagate on this string? m/s Submit Answer Tries 0/2 What is the linear density of the string? kg/m Submit Answer Tries 0/2 What is the tension needed to produce the C note?

8 A 1.0 m1.0 m long pipe held vertically is inserted into a tank of water. This creates an open-closed pipe whose length can be easily varied. When a tuning fork is held at the open end and the pipe is slowly pulled out of the water, resonances are observed when the top of the pipe is 16 cm and 48 cm above the top surface of the water, and no resonances are observed in between. What is the frequency of the tuning fork? Use 340 m/s for the speed of sound. 240 Hz 530 Hz 610 Hz 710 Hz 850 Hz Correct.

A piano wire of linear density 12 g/m has a length 2 m. It is stretched with a force of 7000N. A. What is the third harmonic of vibation of this wire? Draw a diagram. B. By what factor do you have to change the tension to get a fundamental mode at the same frequency.

A one kg mass is hanging on to the pulley of the string, and the string mass density is 0.004 kg/m.  What is the closest value of the velocity of the standing wave string vibration of the given string?
