Science CB Soundwaves
Across
- 3. The change of pitch when a sound source is moving in relation to an observer.
- 9. The study of how sound interacts with structures.
- 11. The highest frequency at which a material vibrates.
- 14. _______________ is the transfer of energy by a wave to the medium through which it travels.
- 15. An acronym for Sound Navigation and Ranging. It is also used by ships.
- 17. ________ can affect sound speed because the particles are packed tightly together and collide to transfer energy quickly.
- 20. The amount of energy that passes through a square meter of space in one second is the _______.
- 21. _____________ is the movement of sound through a medium.
- 23. _______ is how closely particles are packed and can affect the speed of sound waves.
- 24. ____________ occurs when waves that overlap combine, forming a new wave.
- 25. Sound waves carry __________ away from the source as the particles in a medium vibrate.
- 27. A region of a longitudinal wave where the particles in a medium are closest together.
- 28. A ________ is the distance between a point on one wave and the nearest point just like it.
- 29. The lowest frequency at which a material naturally vibrates.
Down
- 1. The intensity and amplitude of a sound wave affects its _________.
- 2. The bouncing of a wave off a surface.
- 4. Many animal, such as bats, use this to communicate.
- 5. The number of wavelengths that pass by a point each second.
- 6. The perception of how high or low a sound seems.
- 7. An __________ is a reflected sound wave.
- 8. Longitudinal waves that can only travel through matter.
- 10. ___________ has many uses, and can be used in the medical field to help treat certain problems.
- 12. A region of a longitudinal wave where the particles are farthest apart.
- 13. The maximum distance the particles in a medium move from their rest positions as the wave passes through the medium.
- 16. A rapid back-and-forth motion that can occur in solids, liquids, or gases.
- 18. A material in which a wave travels.
- 19. As the __________ of a gas increases, the particles move faster and collide more often, making sound waves move faster.
- 22. The collection of reflected sounds from the surfaces in a closed space.
- 23. The unit of measurement that describes the intensity or loudness of sound.
- 26. __________ is an increase in amplitude that occurs when an object vibrating at its natural frequency absorbs energy from a nearby object vibrating at the same frequency.
