Waves

5. shortest time interval during which the motion repeats itself
6. is the change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium from which it originated
7. waves that consist of oscillating electric and magnetic fields that move at the speed of light through space
9. it is calculated as a ratio of how far a wave travels to the time it takes the wave to travel that distance
11. a single disturbance that travel through a medium, where each point along the wave eventually comes to rest
12. number of vibrations per second measured at a fixed point
14. maximum displacement from rest
16. a mixture of the two other types of mechanical waves
17. point that is undisturbed as a result of destructive interference
18. change in direction of waves at boundary between media
20. point of a wave with maximum amplitude

1. wave that causes particles in medium to vibrate to the direction of motion
2. shortest distance between two points where the wave pattern repeats itself
3. a type of EM wave that is utilized mostly for communication, broadcasting, computer networks, etc
4. the displacement of a medium caused by two or more waves is the algebraic sum of the displacements caused by individual waves
8. interaction of waves that occur at the same time
9. a disturbance that transfers energy from one place to another without requiring matter to move the entire distance
10. wave in which motion is parallel to the direction of the wave
13. highest point of each wave motion
15. greek letter used for wavelength
19. lowest point of each wave motion
