Question

part b

a rope has one end tied to a vertical support. you hold the other end so that the rope is horizontal. if you move the end of the rope back and forth with a frequency of 4 hz, the transverse wave you produce has a wavelength of 0.5 m. what is the speed of the wave in the rope?

(a) 8 m/s
(b) 4 m/s
(c) 2 m/s
(d) 0.13 m/s

Answer:

Question 1

• Transverse mechanical waves only
• "When a wave travels through a medium, the particles in that medium vibrate in a direction perpendicular to the direction the wave travels."

• Longitudinal mechanical waves only
• "When a wave travels through a medium, the particles in that medium vibrate in a direction parallel to the direction the wave travels."

• Both transverse and longitudinal mechanical waves
• "The wave speed is equal to the wavelength times the frequency."
• "When a wave travels through a medium, the wave speed will depend on an inertial property of that medium."
• "When a wave travels through a medium, the wave speed will depend on a restoring force in the medium."

Question 2

• (A) 8 m/s
• (B) 4 m/s
• (C) 2 m/s (Correct answer)
• (D) 0.13 m/s
