Basics of Sound
How are sound waves created?
What is Vibration?
The measure of how high or low a sound is?
What is pitch
The body part that vibrates to help humans hear sound?
Are sound waves a type of mechanical or electromagnetic waves?
what is mechanical?
Sound waves can only travel through the air?
What is false?
What state of matter does sound travels the fastest through?
What is a solid?
The Unit used to measure the loudness of Sound?
What is a decibel?
What do bats use in order to navigate their environment and hunt?
What is echolocation?
The reason you hear thunder after lighting is seen?
What is because light travels faster than sound?
Sound waves are electromagnetic.
What is false?
What state of matter does sound travel through the slowest?
What is gas?
The property of a wave that determines pitch?
What is frequency?
The technology that uses sound waves to see underwater?
What is sonar?
What is warm air?
Resonance occurs when an object vibrates more strongly because it is being moved at its natural frequency?
What is True?
The part of a sound wave where the air molecules are close together?
What is compression?
The unit used to measure frequency?
What is hertz (Hz)?
This type of imaging uses high frequency sound waves to create pictures of the inside of the body?
What is ultrasound?
Do sound waves travel longitudinal or transverse?
What is longitudinal?
Sound waves can travel through a vacuum (outer space)
What is False
The part of the sound wave where the air molecules are spread out?
What is rarefaction?
The property of a wave that determines how loud a sound is?
What is amplitude?
What is called when the pitch of a siren of an ambulance or fire truck changes as it drives pass you?
What is the doppler effect?
The speed of sound is about this many meters per second in air?
What is 343 meters per second?
The amplitude of the sound wave determines its loudness?
What is true?
