Across
- 2. - maximum distance particles in a medium move from their rest position as waves pass through the medium.
- 4. - a wave that is a oscillation of matter and transfers energy through a medium
- 5. - passage of light through an object
- 7. metal, cardboard)
- 9. - disturbance is perpendicular to the direction of the wave
- 10. - the distance from one point on a wave to the same point on the next wave.
- 12. - region of a longitudinal wave where the particles are farthest apart
- 17. - bouncing of a wave off a surface
- 19. - a disturbance that transfers energy from one place to another
- 21. - number of wavelengths that pass by a point each second
- 22. - where the displacement of the medium is at a maximum
- 23. - region of a longitudinal wave where the particles in the medium are closest together
- 24. - scatters light as the light passes through (wax paper, frosted glass)
- 25. - wave changes direction, because its speed changes
Down
- 1. - the ability of a material to bounce back after being disturbed
- 3. - can travel through empty space and through matter; includes radio waves, infrared, visible light, ultraviolet, X-rays, and gamma rays
- 5. - where the displacement of the medium is at minimum
- 6. -happens when two or more waves are in the same place
- 8. - material in which a mechanical wave travels
- 11. - angle of incidence equals angle of reflection
- 13. - transmits light (glass, water, air)
- 14. - change of pitch when a sound source is moving in relation to an observer
- 15. - transfer of energy by a wave to the medium through which it travels.
- 16. - a material that reflects or absorbs all of the light that strikes it
- 18. - makes the particles in a medium move parallel to the direction of the wave
- 20. - change in direction of a wave when it travels by the edge of an object or through an opening
