Across
- 2. the transfer of energy by a wave to a medium through which it travels
- 4. a wave in which the disturbance is perpendicular to the direction the wave travels
- 8. the regions of a longitudinal wave where the particles in the medium are closest together
- 12. the bouncing of a wave of a surface
- 13. a wave that can travel only through matter
- 15. makes the particles in a medium move parallel to the direction that the wave travels
- 17. the distance from one point on a wave to the same point on the next wave
- 18. the change in direction of a wave that occurs as the wave changes speed when moving from one medium to another
- 19. a material in which a wave travels
- 20. the lowest point on a transverse wave
Down
- 1. occurs when waves that overlap combine forming a new wave
- 3. the change in direction of a wave when it travels by the edge of an object or through an opening
- 5. the regions of a longitudinal wave where the particles are farthest apart
- 6. the number of wavelengths that pass by a point each second
- 7. a wave that can travel through empty space and through matter
- 9. the maximum distance that the wave moves from the rest position
- 10. the highest points on a transverse wave
- 11. when a wave is reflected from a surface the angle of reflection, is equal to the angle of incidence
- 14. a disturbance that transfers energy from one place to another without transferring matter
- 16. the passage of light through an object
