(a) A wave traveling on a Slinky® that is stretched to 4.5 m takes 2.6 s to travel the length of the Slinky and back again. What is the speed of the wave?
For this one, I did v = d/t
= 4.5 m / 2.6 s
= 1.73 m/s
Then I did v = (1.73)(2) = 3.46 m/s
This is correct
(b) Using the same Slinky stretched to the same length, a standing wave is created which consists of 5 antinodes and 6 nodes including both ends. What is the wavelength of the wave?
I keep getting stuck on this one, and (c) below. I know this answer should be in meters.
(c) At what frequency must the Slinky be oscillating?
I know this answer should be in Hz.
Im not sure which equations to use for (b) and (c)
Any help is greatly appreciated!
