Distance, speed, and time raltionship:
d = 2L = 2(4m) = 8m
t = 2.4 s
A wave traveling on a Slinky® that is stretched to 4 m takes 2.4 s to travel the length of the Slinky and back again.
(a) What is the speed of the wave?
(b) Using the same Slinky stretched to the same length, a standing wave is created which consists of three antinodes and four nodes. At what frequency must the Slinky be oscillating?
