Question

A pulse travelling along a slinky is reflected 3 times (it traverses the slinky from end to end 4 times) in a time of 3.76 seconds. What is the one-way travel time, tp? Answer: Last Answer: 0.63 s Incorrect, tries 3/10. 2. [2pt] Select ALL the correct definitions of the WAVELENGTH of a standing wave. E.g., if B and D are true and the rest are false, enter BD. A) The distance (in the direction of propagation) between adjacent zeros of displacement. B) The distance (in the direction of propagation) between adjacent crests. C) The distance along the standing wave (in the direction of propagation) from one node to the next node. D) The distance along the standing wave (in the direction of propagation) between repetitions of the wave shape.

Explanation / Answer

D) The distance along the standing wave (in the direction of propagation) between repetitions of the wave shape.
