Question

1. For a certain transverse wave, the distance between two successive crests is 1.20 m, and eight crests pass a given point along the direction of travel every 12.0 s. Calculate the wave speed. 10 pts



2. A sinusoidal wave is traveling along a rope. The oscillator that generates the wave completes 40.0 vibrations in 30.0 s. Also, a given maximum travels 425 cm along the rope in 10.0 s. What is the wavelength? 10 pts





3. A piano string having a mass per unit length equal to 5.00 x10-3 kg/m is under a tension of 1350 N. Find the speed of a wave traveling on this string. 10 pts

Explanation / Answer

1)7*1.2/12 = 0.7 m/s 2)42.5*3/4= 31.87 3)sqrt(1350/0.005)= 519.615...
