2) The wave functions for two waves traveling in the same direction on a string are described below: Y(x,t) = 0.2 sin (8x - 50t) and Y2(x, t) = 0.2 sin(8x – 50t + n/3) where, y and x are in meters, and t is in seconds. An element of the string at x =0 would have a maximum transverse speed of: (a) 6.25 m/s (b) 10 m/s (c) 17.3 m/s (d) 19.3 m/s 3) A sinusoidal transverse wave has a wavelength of 2.8 m. It takes 0.1 s for an element of the string at a position x to move from the maximum position of ymar = 0.03 m to the equilibrium position y = 0. What is the period of the wave, T. and the wave speed. v? (a) 0.4 sec: 28 m/s (b)0.8 sec: 14 m/s () 0.4 sec: 7 m/s (d)0.8 sec: 3.5 m/s Page 1 / 4 +
