Question

3. A) A particle undergoing simple harmonic oscillation of period T is Xm at t = 0. Draw the simple harmonic motion of that particle. What would be its position when t = 10000.85 T (2) B) If mass of that particle is 500 gm and angular frequency is 3 rad/sec. What would be the total energy of the particle when the amplitude is 10 cm? (2) C) Fig. shows two travelling waves moving along + x axis on the string with the same speed of 10 m/s. 1) Find the wavelength and wavenumber of each travelling wave. (1.5) 2) What is the amplitude of each wave? (0.5) 3) Determine the frequency and angular frequency of each wave. (1) 4) Which wave has the maximum transverse speed of a particle on the string larger? (1.5) y (cm) 4.0 B A 0 1.0 x (m) 2.0 -4.0 D) Two waves with same amplitude and wavelength are interfering with each. What kinds of interference would you expect if their phase difference in terms of wavelength is 1) ? = 0.55 2) ? = 0.85 (1.5)
