- Having some trouble understanding this question: a and b Please see attached image Caroline, a piano tuner, suspects that a piano's D4 key is out of tune. Normally, she would play the key along with her D4 tuning fork and tune the piano to match, but her D4 tuning fork is missing. Instead, she plays the errant key along with her C4 tuning fork (which has a frequency of 261.6 Hz), displays the resulting waveform on a handheld oscilloscope, and measures a beat frequency of 50.3 Hz. Then, she plays the errant key along with her E4 tuning fork (which has a frequency of 329.6 Hz) and measures a beat frequency of 17.7 Hz. a. What frequency is being played by the out‑of‑tune key? 211.3 Hz 311.9 Hz 18.2 Hz 347.3 Hz 279.3 Hz b. If the D4 key is supposed to produce a frequency of 293.7 Hz, is the frequency of the key lower than it should be ("flat") or higher than it should be ("sharp")? flat sharpConsider the waves in Figure 17.8 to be waves on a stretched string. Define the velocity of elements of the string as positive if they are moving upward in the figure. (i) At the moment the string has the shape shown by the red-brown curve in Figure 17.8a, what is the instantaneous velocity of elements along the string? (a) zero for all elements (b) positive for all elements (c) negative for all elements (d) varies with the position of the element (ii) From the same choices, at the moment the string has the shape shown by the red-brown curve in Figure 17.8b, what is the instantaneous velocity of elements along the string?Suppose that y1(x,t) and y2(x,t) are two independent wave functions, which describe the displacements vertical (in meters) of a string, as a function of position x (in meters) and time t (in seconds): (See image) For what values of the phase constant ϕ1 does destructive interference occur?
