Sound Wave Basics
Sound is the back-and-forth movement of what?
What is particle vibration?
When sound disturbs the air, what do the air particles do?
What is vibrate?
What is the material in which particles vibrate called?
What is the medium?
In the slinky model, what did one coil marked with yarn represent?
What is a single air particle?
High-density regions in a sound wave are called what?
What are compressions or disturbances?
What does density describe?
What is how tightly packed matter is (mass per volume)?
Do air particles travel all the way from the sound source to the listener?
What is no; each vibrates near its original position?
Sound can travel through solids, liquids, and gases if their particles can do what?
What is vibrate and transfer energy?
In the slinky experiment, what did the quick push represent?
What is a sound disturbance?
What does the candle flame represent?
What is an individual air particle?
A sound wave is a series of what in a material medium?
What are high- and low-density regions?
What kind of wave has particles vibrating parallel to the direction the disturbance travels?
What is a longitudinal wave?
In a vacuum, can sound travel?
What is no?
How is sound energy transferred through a material?
What is through collisions between neighboring particles?
At a baseball game, who hears the bat hit the ball first: the catcher or an outfielder?
Who is the catcher?
What is the name for a picture showing high- and low-density regions in a sound wave?
What is a density diagram?
Sound is which kind of wave: transverse or longitudinal?
What is longitudinal?
Would you hear an explosion in space?
What is no?
In the slinky model, what traveled along the slinky: the marked coil or the disturbance?
What is the disturbance; each coil vibrated near its original position?
What two patterns can a density diagram show in a sound wave?
What are alternating high- and low-density regions?
Explain how particle vibration creates a sound-wave pattern.
What creates alternating high- and low-density regions that travel through the medium?
Describe particle motion in a longitudinal sound wave.
What is back-and-forth vibration parallel to the direction the disturbance moves?
Why cant sound travel through space? Use the word “medium.”
What is sound needs a material medium with particles to vibrate and transfer energy?
How can sound energy reach a receiver if air particles do not move all the way from the source?
What is neighboring particles collide and pass energy along through the medium?
Why does the catcher hear the bat sooner than an outfielder?
What is the catcher is closer, so sound energy reaches them sooner through the air?
