Physical Science Part 6 Sound Study Guide answers
1 Sound is vibrations you can hear.
2. To produce sound, an object must vibrate.
3. Sound can be transmitted or travel in waves.
4. Pitch measures how high or low a sound is. The faster a vibration is, the higher the pitch.
5. An example of a low pitch would be: barking like a dog. An example of a high pitch would
be squeaking like a mouse.
6. Volume is the loudness of a sound.
7. Compression is the part of a sound wave in which the air is pushed together. (Think of a
slinky bunched up.)
8. A sound wave is a moving pattern of high and low pressure that you can hear.
9. Amplitude is the measure of the strength (tallness) of a sound wave. A taller wave stands for
a higher sound.
10. Wavelength is the distance from one wave to the next in a sound wave.
11. Sound waves travel away from the vibrating object in all directions.
12. Sound waves travel through solids, liquids and gases.
13. The more objects a sound wave must travel through, the more the wave is broken up or
lowered.
14. The farther you are from the source of a sound, the softer the sound will be.
