In Lesson 1, we saw that the sound coming from the speaker in the truck could:
create light that reflects from the windows.
make the windows stop vibrating/shaking.
only be heard and felt inside of the truck.
make the windows of the building vibrate/shake.
What would we observe when a sound source makes a sound?
We will see the sound waves leaving the source.
We will see the sound source vibrating.
We will see the sound source changing colors.
We will see the sound source being pushed.
Sound is produced by:
moving air.
turning up the volume.
rotation.
vibration.
When a force is applied to an object, such as an instrument, __________ is transferred.
energy
