(b) What a re the amplitude and phase constant of the wave? (c) Write the equation for the displacement D ( x, t ) of the traveling wave. (d) What is the strings displacement at x = 0 . 50 m and t = 15 ms? 1 - 1 Problem 4 A 2 . 0-m-long string vibrates at its second-harmonic frequency with a maximum amplitude of 2 . 0 cm. One end of the string is at x = 0 cm. Find the oscillation amplitude at x = 10 , 20 , 30 , 40 , and 50 cm. Problem 5 An open-open organ pipe is 78 . 0 cm long. An open-closed pipe has a fundamental frequency equal to the third harmonic of the open-open pipe. How long is the open-closed pipe? 1 - 2...
