A violin string of length 43 cm and mass 1.1 g has a frequency of 495 Hz when it is vibrating in its fundamental mode. (a) What is the wavelength of the standing wave on the string? cm (b) What is the tension in the string? N (c) Where should you place your finger to increase the frequency to 645 Hz? cm from the fixed end of the string (from the peg of the violin)
A violin string of length 38 cm and mass 1.3 g has a frequency of 457 Hz when it is vibrating in its fundamental mode. (a) What is the wavelength of the standing wave on the string? cm (b) What is the tension in the string? N (c) here should you place your finger to increase the frequency to 607 Hz? cm from the fixed end of the string (from the peg of the violin) eBook
A violin string of length 44 cm and mass 1.1 g has a frequency of 534 Hz when it is vibrating in its fundamental mode. (a) What is the wavelength of the standing wave on the string? _______ cm (b) What is the tension in the string? _______N (c) Where should you place your finger to increase the frequency to 684 Hz? __________ cm from the fixed end of the string (from the peg of the violin)
A steel violin string vibrates at a fundamental frequency of 440 Hz. The length of the string, which is half a wave length of the fundamental mode, is 0.33 m and the mass of the string is 0.36x10-3 kg. The velocity of transverse waves = ______m/s
The A string of a violin is 34 cm long between fixed points with a fundamental frequency of 440 Hz and a mass per unit length of 6.2×10−4 kg/m . What is the wave speed in the string? What is the tension in the string? What is the length of the tube of a simple wind instrument (say, an organ pipe) closed at one end whose fundamental is also 440 Hz if the speed of sound is 343m/s in air?...
A violin string vibrates with a frequency of 440 Hz in the fundamental mode. With what frequency will the string vibrate if 5 loops are observed? ____________Hz
A violin string has an initial tension of 45.0 N. When playing the note B on the violin, the frequency is found to be 509 Hz. This note should actually have the frequency 494 Hz, so the player changes the tension to get the correct frequency. What is the new value of the tension? Give your answer to three significant figures.
What is the frequency of the fundamental mode of vibration of a steel piano wire stretched to a tension of 440 N? The wire is 0.600 m long and has a mass of 5.60grams.234 Hz517 Hz312 Hz366 Hz295 Hzi tried using this equation- v = √tension / √mass per unit lengthso v = √440 / √5.6/0.6 = 6.87 m/sthen i plugged that into f1 = 1/2(L) * vsof1 = 1/2(0.6) * 6.87m/s = 5.721... which is way wrong. what am...
The G string on a violin has a fundamental frequency of 196 Hz. It is 31.0 cm long and has a mass of 0.500 g. While this string is sounding, a nearby violinist effectively shortens the G string on her identical violin (by sliding her finger down the sting) until a beat frequency of 4.00 Hz is heard between the two strings. When that occurs, what is the effective length of her string? ___cm (please write solution legibly)
