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