question 4-7 4. Travelling Waves and Their Characteristics A rope wave travels in the positive x -direction. You are also told that the speed of the wave is 1000 cm/s, its frequency is 200 Hz, and that the wave is subject to the following initial conditions: at x 0 and t = 0: y =-1 cm, and, at x = 0 and t : ar = +20 cm/s (this is the velocity of the point on the rope at horizontal...
(4%) Problem 13: Using special techniques called string harmonics (or "flageolet tones"), stringed instruments can produce the first few overtones of the harmonic series. While a violinist is playing some of these harmonics for us, we take a picture of the vibrating string (see figures). Using an oscilliscope, we find the violinist plays a note with frequency f=815 Hz in figure (a). Otheexpertta.com A 14% Part (a) How many nodes does the standing wave in figure (a) have? 14% Part...
Thank you and I appreciate your help and time in advance! L = N (l/4), N = 1, 3, 5 … (1) Where L is the length of the air column and N is an odd integer. When N = 1, the column has a length one quarter of wavelength with a node at the water surface and an antinode at the opening. Then the wavelength L1= (1/4) l, or l= 4L1. (2) When N = 3, with...
