Across
- 5. waves that travel through matter or empty space
- 6. wavelength times frequency
- 8. Distance between one point to the nearest point in the wave
Down
- 1. mechanical wave that causes particles in matter to move back and forth
- 2. needs a medium to travel through
- 3. mechanical wave that causes particles in matter to at right angles
- 4. Number of wavelengths that pass a given point in one second
- 7. object that the waves travel through
- 9. One half distance between crest and trough in traverse wave
- 10. SI unit for frequency
