24. what is the number of occurrences of a repeating event per unit time
25. what is it called when a light beam rebounds after hitting a surface
26. what is the increase or decrease in the frequency of sound, light, or other waves as the source and observer move toward or away from each other

1. what is the production of an electromotive force across a conductor when it is exposed to a varying magnetic field
3. what is the time needed for one complete cycle of vibration to pass a given point
5. what is it called when a light beam bends after hitting a surface
6. what is a wave in which particles of the medium move in a direction parallel to the direction that the wave moves

19. what is an object called if it is being lit by another object
20. will tend to bring the system back toward equilibrium
21. what is a region around a charged particle or object within which a force would be exerted on other charged particles or objects
