Across
- 3. a sound or series of sounds by the reflection of sound waves
- 4. human perception of sound volume depends on intensity
- 7. measure of sizes and disturbance of a wave and the energy it carries
- 14. the distance between 1 point on a wave and the nearest point just like it
- 15. a repeating disturbance that transfers energy through matter of space
- 18. when mixing of 2 waves add together
- 20. highest point on the transverse wave
Down
- 1. unit for sound intensity
- 2. a wave that's matter in medium forces move back and forth a long direction of wave
- 5. bending of waves around obstacles
- 6. when waves come together and cancel each other out
- 8. reflection from smooth surface and the angle of the reflected ray is equal to the angle of incident ray
- 9. number of wavelengths that pass a point each second
- 10. angle between ray incident and line perpendicular to the surface
- 11. waves that can travel only through matter
- 12. ride a surfboard with all 10 toes curled over the boards front edge
- 13. SI unit of frequency
- 16. the amount of time it takes one wavelength to pass a point
- 17. matter through which a wave travels
- 19. dense region of longitudinal wave
