Answer:
24-e measures distance from axis of wave to height (do last if difficult)
25-b lowest point on wave
26-d height of wave from axis (zero height) of wave
27-a distance of one wavelength - from part of wave to identical part
28-c speed of vibration of wave - actual numeric number
29-f measure of speed of vibration - usually vibrations / second (note one could specify megahertz or million vibrations/sec - a description of vibration of the wave as opposed to numeric vibrations/second)
