Sci Ch 10 Unit Test
Earth Science chapter 10 Unit Test
| Question | Answer |
|---|---|
| membrane that vibrates the bones of the middle ear. | Eardrum |
| fluid filled structure of the inner ear that contains hair cells. | Cochlea |
| is the amount of energy that passes through a certain area in a specific amount of time. | Intensity |
| the way the brain perceives the intensity of a sound. | Loudness |
| the highness or lowness of a sound. | Pitch |
| the change in pitch of sound caused by motion of either the sound source or receiver. | Doppler effect |
| is any collection of sounds that are deliberately used in a regular pattern. | Music |
| multiple of the fundamental frequency. | Overtone |
| the part of the violin that amplifies the sound of the springs. | Resonator |
| is the study of sound. | Acoustics |
| is the process of locating objects by emitting sounds and then interpreting the sound waves that are reflected from those objects. | Echolocation |
| is a system that uses the reflection of underwater sound waves to detect objects. | Sonar |
| sound with frequencies above 20,000 Hz. | Ultrasonic waves |
| difference between sounds of the same frequency caused by overtones. | Quality |
| unpleasant echo effect caused by many sound reflections. | Reverberation |
| Graph; Label the ear | Outer ear, middle ear, inner ear, cochlea, Eardrum |
| An increase in temperature will_____the speed of a sound wave. | Increase |
| The pitch of the siren of a rapidly approaching fire truck will_____. | Increase |
| Increasing the frequency of a sound wave will change the____of a sound. | Pitch |
| We cannot hear the sounds made by some heavy machinery because the frequencies are in the_____range. | Infrasonic |
| Compare and contrast noise and music. | Noise has random patterns and pitch. Music has sounds that are deliberately used in a regular pattern. |
| Ear graph: Steps | 1 ear gathers compressional waves 2 ear amplifies the waves 3 the amplified waves are converted to nerve impulses that travel to the brain 4 the brain decodes and interprets the nerve impulses |
| In a science fiction movie a nearby spaceship explodes and you hear the explosion on your ship. Is this realistic? | You can't hear sound in space because there is no matter to go through. |
| A train is blowing its whistle as it is approaching you at a crossing what happened to the whistles Intensity, Speed, Frequency, and Wavelength. | Intensity and speed stay the same Frequency increases and Wavelength decreases |
| If the amplitude of a sound wave decreases what happens to its Loudness, Intensity, Pitch and, Speed. | The Loudness and Intensity decreases and the Pitch and Speed stays the same. |
| The Low and High Amplitude Graph; 1. When the compression of amplitude is less compressed: 2. When the compression of an amplitude is more compressed: | 1. Low Amplitude 2. High Amplitude |
