WorksheetsInteractions of Sound Waves
Total questions: 10
Worksheet time: 3mins
What is a medium?
What waves travel through, and can determine the speed of the waves
The formula for speed
The middle of two objects
A classification of animal species
How does temperature affect the speed of a sound wave?
Allows the wave to travel to space
Completely stops the waves travel
Higher temperatures allow it to travel faster, lower temperatures allow it to travel slower
Lower temperatures allow it to travel faster, higher temperatures allow it to travel slower
What material reflects sound waves?
Hardwood floors
Curtains
Silver plate
Chair
What material absorbs sound waves
Trump tower
Fabric curtains
Painted ceilings
Hardwood Floors
What is an echo?
A loud sound
A quiet sound
A reflected sound wave
What dolphins use to communicate
What is interference?
A certain point of speed
Beats
Sounds that can hurt your ears
The interaction of two or more sound waves
What is constructive and destructive interference?
Waves overlap and combine to form a new wave with larger amplitude; waves combine to form a sound with smaller amplitude
Sound waves that humans cannot hear
Waves combine to form a sound with smaller amplitude; waves overlap and combine to form a new wave with larger amplitude
The malfunction of satellites and computers
What is a sonic boom?
Sound that has the ability to damage human ears
A sound that occurs when jet planes move faster than the speed of sound
The lowest sound with the lowest frequency
When a sound wave passes 20,000 hz
What is resonance?
A sound wave matches the natural frequency of an object and causes the object to vibrate
A sound wave that causes objects to break
The sound of someone shouting behind you
The sound of someone shouting in front of you
How is resonance important to making music?
It makes larger/louder sounds
The amplitude increases
It can control the sound of the instrument
Blowing air into a mouthpiece causes vibrations, and the sounds get louder when it forms a standing wave inside the instrument
