Be careful to input your answer as a string of 5 Ts and Fs, in order. (No spaces or any other characters) Correct, computer gets: TTTFT fn 6. [1pt] We know that when we pluck a string on an instrument the resulting sound wave travels through the air at a speed of (about) 344 m/s. But the wave moving on the STRING itself doesn't have to travel at 344 m/s. Let's consider some of the things that affect the velocity of a standing wave on a string: decide whether each of the following statements are T-True, or F-False. (If the first is T and the rest are F, enter TFFFF) A) The velocity of a wave traveling on a double bass string is increased if you exchange the string for one that is less dense (keeping the length and tension unchanged.) B) Given that waves travel on a banjo string with speed less than the speed of sound in air, and that a banjo string vibrates with frequency f: (T or F) the fundamental frequency of sound produced by the banjo will be smaller than f. C) The velocity of the wave traveling on a string stays the same if you increase the length of the string (keeping the type of string, and the tension of the string, unchanged) D) The velocity of the wave traveling on a string is higher if you pluck the string with a slightly larger sideways force E) Given that waves travel on a mandolin string with speed less than the speed of sound in air, and that a mandolin string vibrates with a wavelength lambda: (T or F) the resulting sound wave produced in the air will have a wavelength longer than lambda. Be careful to input your answer as a string of 5 T's and F's, in order. (No spaces or any other characters) Answer: Submit All Answers Last Answer: FFTTT Not yet correct, ONE try left!! Hint: If you struggle with some of these questions, you might consider trying the NEXT problem and see if that helps you! 7. [1pt] A typical steel B-string in a guitar resonates at its fundamental frequency at 240 Hertz. The length of the string is 0.680 m. What is the wave velocity along the string?

[1pt] The diagram represents a snapshot of a standing transverse wave on a flexible guitar string taken when the displacement is at a maximum. (Note: the vertical scale is very exaggerated, the actual sideways displacement of the string is negligibly TINY compared to the length of the string!) The string is 0.80 m long with tension 7.00 N. The total mass of the string is 0.013 kg. Find the wavelength of this standing wave in meters (but do not enter units) m Answer: Incorrect, tries 4/6. Submit All Answers Last Answer: 25.94
