Suppose that you find the fundamental frequency at 45.0 Hz. This means that the entire string...
Question 20 If 300 Hz is the fundamental frequency of a standing wave on a string, what is the frequency of the 2nd harmonic? 100 Hz 150 Hz 300 Hz 600 Hz 900 Hz
Find the following: a) If a violin string has a fundamental frequency of 500 Hz then what frequency can set the string into a resonant vibration (standing wave pattern)? b) A cannonball is fired horizontally at 5 m/s from a cliff. What is the magnitude of the total velocity 2 s later?
Suppose that the frequency of an ideal spring at the first harmonic is 20.0 Hz and the wavelength of the wave is 4.0 m. At the fourth harmonic, what would be the wavelength, the frequency, and the speed of the wave? The frequency of the standing wave when there is one loop is called the fundamental frequency of the first harmonic. In general, what statement can be made about the degree to which the frequency at each of the harmonics...
Suppose you have a standing wave with three nodes and two anti-nodes (two vibrating segments). and the trequency is 60.0 Hz. You turn the knob on the controller so that the frequency now reads 55 Hz. How many anti-nodes do you expect to see? If the pattern is no longer a standing wave, this means 0 anti-nodes. I expect to see anti-nodes
A string, stretched tight, is observed to vibrate with a fundamental frequency of 50 Hz. We then vibrate the string at the frequencies shown below. Which frequency would NOT produce a standing wave on the string? Not enough information to determine 200 150 100 25
Resonance of a String: A cello string is 60 cm long with a fundamental frequency of 486 Hz. Show means do the calculation for wavelength and speed using the (PSF). Show the fundamental wavelength is 1.20 meters. Show the speed of the wave is 583 m/sec. Draw the fundamental vibration to scale. Use 1 cm = 5 cm. Draw the first 3 overtones to the same scale, arranging the diagrams neatly as in class. Give frequency and wavelength of each...
You have a string with a mass of 12.9 g. You stretch the string with a force of 9.19 N, giving it a length of 1.95 m. Then you vibrate the string transversely at precisely the frequency that corresponds to its fourth normal mode, that is, at its fourth harmonic. What is the wavelength of the standing wave you create in the string? What is the frequency? Wavelength? (m) Frequency? (Hz)
Problem 2 [8 pts] Oscillator As a quality control technician at a violin string factory, you cut a sample of E-string off a large roll. The sample that you cut has a mass of ms = 1.021 grams and a full length of 2.5 meters. To test the string, you stretch some of it across a length L = 0.35 m, applying tension by means of a hanging mass m (as pictured). A variable frequency oscillator is used to excite...
Suppose on a string of length L=87 cm, tension T=115 N, and mass m the fundamental (1st Harmonic) has a frequency of f1= 500.0 Hz. a) What is the wavelength of the fundamental? b) What is the speed of propagation of the wave in the string? c) What is the mass m of the string? d) In order to tune the string to a new fundamental frequency of 505 Hz, how much does the tension need to change? Will it...
Questions: 1. Explain how you can raise the pitch of a note on a guitar by altering the string’s (a) length, (b) tension, or (c) thickness or mass. Be very specific about what you would do to raise the pitch. 2. If the fundamental frequency of a guitar string is 250 Hz, what is the frequency of the second harmonic? Of the third harmonic? Explain. 3. Consider a vibrating guitar string. The loudest harmonic is the fundamental, but many higher...
