Musical Instruments: A man wants to learn to play guitar. He finds a model he likes for $559. He places a finger on a string so that 0.52 m of the string is free to vibrate, but clamped at both ends. He does not know it, but the speed of waves in the string is 235 m/s. (a) When he plucks the string, what pitch (frequency) will it produce? (b) The man really likes the guitar- and the note he played. He still has $13.96 after his purchase, so he buys some wood to build a resonant cavity to amplify this sound: a wooden box open at one end. How long should he make the box? Assume the speed of sound in air is 340 m/s.

Fluid Dynamics

The study of the flow of gases and liquids, usually in and around solid surfaces, is known as fluid dynamics in physics and engineering. Fluid dynamics, for example, can be used to evaluate the movement of air through an airplane wing or the surface of a vehicle. It can also be used in ship design to increase the speed at which ships pass through water.

Question

**Musical Instruments:**
A man wants to learn to play guitar. He finds a model he likes for $559. He places a finger on a string so that 0.52 m of the string is free to vibrate, but clamped at both ends. He does not know it, but the speed of waves in the string is 235 m/s.

(a) **When he plucks the string, what pitch (frequency) will it produce?**

(b) **The man really likes the guitar — and the note he played. He still has $13.96 after his purchase, so he buys some wood to build a resonant cavity to amplify this sound: a wooden box open at one end. How long should he make the box?**

Assume the speed of sound in air is 340 m/s.

You are learning to play the violin. One end of the string is vibrating from the bow running along one end. The other end is tied down. The length of the string we will be looking at is 30 cm and the total mass of the string is 0,32 g. We will be modeling this as a standing wave on a string. You being to play the violin and play a note which has a frequency of 440 Hz. You (having incredible eyesight) see that there are 3 anti-nodes on the string forming a perfect sinusoidal wave (shown in diagram). L i) What is the wavelength of this standing wave? ii) What is the speed of the traveling waves that make up this standing wave? iii) What is the tension of the string? iv) Suppose you increase the tension of the string until you get a new standing wave. Will this standing wave have two antinodes or four antinodes? Explain. (You are still at a frequency of 440 Hz)
