- K 2. Resonances in a Tube A student is given a tube of unknown length and cannot tell whether the ends of the tube are open or closed. Given a tunable sound generator the student measures the frequencies of the two lowest resonances in the tube to be 235 Hz and 587 Hz. a. Explain why this student must be mistaken in the measurement. b. Is it possible that the student measured the lowest frequency correctly and simply missed some resonances between the two given above? If so, what would those missed frequencies be and what conclusion about end conditions can you reach? If not, why not?arrow_forwardQUESTION 2 Which of the following media cannot support a transverse wave? a. The atmosphere b. A steel bar O c. An aluminum rod d. The crust of the earth e.

- Group Problem Chapter 18 Two sinusoidal waves in a string are defined by the wave functions with x and y in cm (so k is in rad/cm) and t in s. yı(x,t) = 2.10 sin (18.0x – 31.0t) y2(x,t) = 2.10 sin (30.0x – 45.0t) a) What is the phase difference between these two waves at the point x1=5.00cm and tj=2.00s? (Pick an angle between 0° and 360°.) b) What is the positive x value closest to the origin for which the two arguments differ by +(2n+1)n at t1? At that location the two waves destructively interfere. (Hint: it's not the n=0 case!)arrow_forwardSuperposition and Standing Waves A standing wave occurs when two travelling waves with the same wavelength and wave speed pass through each other in opposite directions. Mathematically the first wave is written as: Y, (x, t) = A cos(kx – wt) and the second wave: Y,(x, t) = A cos(kx + wt) where the wave number, k = 2/2, the natural frequency w = 27/r, and A and T are the wavelength and period of the waves, respectively. The positive and negative signs of w show that the waves are travelling in opposite directions. Demonstrate that the sum of these two waves, Ysum = Y1 + Y2, results in a sinusoidal wave, Y(x) with a wavelength A and an amplitude that is twice that of each wave individually. Furthermore, as time advances, the amplitude is oscillating between +A and -A with a period, T. Repeat the summation, only now assume the other harmonic wave form: Y, (x, t) = A sin(kx – wt) and the second wave: Y2(x, t) = A sin(kx + wt) The following trigonometric identities may be helpful: sin(a +…arrow_forwardment PRINTER VERSION 1 BACK NEXT Chapter 16, Problem 024 GO A wave traveling along the x axis is described mathematically by the equation y = 0.17sin(2.3nt + 0.68nx), where y is the displacement (in meters), t is in seconds, and x is in meters.
