Across
- 3. highest point in sound wave where more sound particles exist (loudest point)
- 4. push or pull
- 8. ability for an object to exert force and do work
- 9. the number of times per second that a sound pressure wave repeats itself - measures pitch
- 13. 2 or more atoms.
- 16. the intensity of a sound. Measured in decibels
- 17. pattern of disturbance caused by the movement of energy traveling through a medium
- 18. The measure of the height of the sound wave - measures loudness
- 19. something that detects sound
- 20. to change its shape by applying force
- 21. change in the direction of a wave
- 22. repeated back and forth motion of a particle
- 24. Hollow fluid-filled tube in the inner ear that carries sound to the brain. Contains nerves
Down
- 1. lowest point in a sound where less sound particles exist (lowest point - break in sound)
- 2. region in a wave where particles are close together
- 5. Anything that has matter. Anything that is made of atoms or molecules.
- 6. Substance that allows sound to travel through
- 7. How heavy something is for it’s size. Comparison of mass and volume (Density = Mass/Volume)
- 10. Thin membrane (skin) in the ear that separates the outer ear from the inner ear. Vibrates when it detects sound
- 11. a device that identifies sounds, such as tones and beeps, from various sources
- 12. Anything composed of atoms or molecules. Anything that occupies space.
- 14. an instance of one moving object or person striking violently against another
- 15. Distance between two identical points on a wave
- 17. Tiny hairs on sensory cells in the inner ear that are essential for hearing and balance. Convert forces from sound into electrical signals
- 23. Smallest form of matter. Cannot be broken down chemically. Basic building block of matter
