Chapter 7

3. (wave) two waves of the same frequency and amplitude travelling in opposite directions superimpose to create stationary regions of maximum and minimum displacement
4. the addition of overlapping waves in the same medium
7. the magnitude of an oscillation’s maximum value from the neutral point within a wave
11. the number of cycles completed per second
13. wave sources that create waves of the same frequency and constant phase difference in the same medium
14. the transmission of energy via oscillations from one location to another without the net transfer of matter
16. (wave) a wave that propagates through a medium, carrying energy from one location to another
17. the time taken to complete one cycle

1. a wave in which the oscillations are parallel to the direction of wave travel and energy transmission
2. the distance covered by one complete wave cycle
5. difference: the difference in distance travelled by two waves from their sources to the same point
6. superposition creating a larger (constructive) or smaller (destructive) resultant wave
7. a point where constructive interference consistently occurs
8. a wave in which the oscillations are perpendicular to the direction of wave travel and energy transmission
9. the spread of a wave around an obstacle or through an aperture
10. (frequency)the lowest frequency of a standing wave that will form in a given medium
12. a point where destructive interference consistently occurs
15. a hole, gap, or slit through which a wave travels
