A. 20 cm B. 40 cm C. 60 cm D. 90 cmFor questions 6-8, refer to the problem below. A student takes a 30.0 m-long string and attaches one end to the wall in the physics lab. The student then holds the free end of the rope, keeping the tension constant in the rope. The student then begins to send waves down the string by moving the end of the string up and down with a frequency of 2.00 Hz. The maximum displacement of the end of the string is 20.00 cm. The first wave hits the lab wall 6.00 s after it was created. 6. What is the speed of the wave? A. 1.00 m/ s B. 3.00 m/s C. 5.00 m/s D.7.00 m/s 7. What is the period of the wave?

How long does it take a wave of frequency 0.2 Hz and wavelength 2 m to travel along a rope of length 4 m? A. 4 s B. 6s C. 8 s D. 10 s 10. The distance between the two troughs of the water surface waves is 20 m. An object floats on the surface of the water so that it experiences the vibration motion. If the time to travel one vibration is 4 seconds, then what is the velocity of wave in m/s? A. 5 B. 6 C. 7 D. S 11. The graph below displays the displacement of a point in one medium as a function of time when a wave passes through the medium. If the wavelength is 6 meters, then what is the speed of the wave propagation? A. 3 m/s B. 6 m/s C. 8 m/s D. 12 m/S 12.
