Across
- 2. a disturbance that transfers energy from one place to another
- 6. waves- a wave that moves perpendicular to the direction of the wave
- 9. lowest part of wave
- 10. interference- when waves add up to make a larger amplitude
- 15. wave bounces off and goes into new direction
- 16. - highest part of wave
- 18. - the wave bends around an object
- 19. - the height of the wave
- 21. interference- when waves add up to make a smaller amplitude
- 23. of reflection-the angle at which the reflected ray bounces off the surface
- 24. speed- the distance a wave moves in a certain amount of time
Down
- 1. - the length from top of wave to top of wave
- 3. - the wave is absorbed and disappears.
- 4. a type of material through which the wave travels
- 5. wave- radio waves, microwaves ,UV
- 7. - particles which are close
- 8. of incidence- the angle formed between the normal and incident ray at the point of incidence
- 11. - the wave bends as it passes through an object
- 12. waves- a wave that travels along the surface of a medium
- 13. what frequency is measured in
- 14. wave- a type of wave which moves parallel to the direction of the wave
- 17. - number of complete waves that pass a given point per sec
- 20. wave- it needs a medium to travel through
- 22. - particles which are far
