In a slinky spring lying straight on a table, a longitudinal wave is produced. At one instant, 5 successively spaced compressions occupy a total length of 1.5m. Later, 40 compressions are counted to pass a fixed point in 8s.
a. (a) Calculate the wavelength of the wave.
b. (b) Determine its frequency.
c. (c) Hence find the speed of the wave.
