**(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

= 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!
