Across
- 5. an up-and-down or back-and-forth motion
- 10. one-half the distance between a wave's high point and low point
- 11. the transfer of energy from a wave to matter as the wave passes through it
- 13. waves that move through matter
- 14. when waves bounce off a surface
- 16. our perception of sound wave frequency
- 17. states that waves get reflected at the same angle as the angle that it moved toward the barrier
- 21. waves that move through vacuums
- 22. measured from a point on one wave to the same point on the next wave
- 23. combine to form a larger wave
Down
- 1. oscillate in the same direction as it moves
- 2. number of waves that pass a fixed point in a given unit of time
- 3. cancel each other out
- 4. bending of waves as they travel through different mediums
- 6. the wavelength and frequency range of electromagnetic waves
- 7. used to measure the loudness, or intensity of sound
- 8. bending of waves around a barrier past small openings
- 9. oscillations that carry energy
- 12. the time it takes a wave to move from one point to another
- 15. a result of waves colliding with each other
- 18. oscillate perpendicular to the direction of motion
- 19. how much energy a sound wave carries
- 20. space that has no matter in it
