Problem 7: The D-string on a properly tuned guitar produces a tone with a fundamental frequency of 146.8 Hz. The oscillating length of a D-string on a certain guitar is 0.62 m. Part (a)_What is the wavelength, in meters, of the standing wave in the D-string when it is oscillating at its third harmonic (also called its second overtone)? ie Summary 13 = 74.8 Deduction Potemual sin() cos() tan() 8 9 НОМЕ Submissions E 1^ Attempts remaining: 9 er attempt) cotan() asin() acos() 4 5 6 atan() acotan() sinh() 1| 2 * 3 detailed view cosh() tanh() cotanh() END O Degrees O Radians VOI BACKSPACE CLEAR Submit Hint Feedback I give up!
