Across
- 2. lowest point on a transverse wave
- 4. maximum distance particles in a medium move from it's rest position
- 7. transfer of energy by wave
- 9. number of wavelengths that pass by a point each second
- 10. bouncing of a wave off it's surface
- 11. transfers energy from one place to another
- 14. overlapping waves
- 15. highest point on a transverse wave
Down
- 1. passage of light through an object
- 3. can travel through empty space and matter
- 5. angle of incidence equals angle of reflection
- 6. perpendicular to or forming a right angle
- 8. wave changes direction because it's speed changes
- 12. travels only through matter
- 13. mechanical waves travel in_______
