100
a disturbance in matter that carries energy from one place to another
What is a mechanical wave?
100
the distance between a point on one wave in the same point on the next cycle of the wave
What is wavelenght?
100
a wave bounces off a surface that it can not pass through
What is reflection?
100
longitudinal waves that travel through a medium
What are sound waves?
100
a technique for determining the distance to an object under water
What is sonar?
200
the material through what a wave travels
What is a medium?
200
any motion that repeats at regular time intervals
What is perodic motion?
200
the bending of a wave as it enters a new medium at a right angle
What is Refraction?
200
the rate at which a wave's energy flows through a given area
What is intensity?
200
a changed in sound frequency cause by motion of the sound source, motion of the listener, or both
What is doppler effect?
300
a repeating back and forth motion
What is a vibration?
300
the number of complete cycles in a given time
What is frequency?
300
the bending of a wave as it moves around an obstacle or passes through a narrow opening
What is diffraction?
300
a physical response to the intensity of sound modified by physical factors
What is loudness?
300
A part of the ear that gathers and focuses sound
What is outer ear
400
a wave that causes the medium to vibrate at right angles to the direction in which the wave travels
What is a transverse wave?
400
speed=Wavelength X Frequency
What is the formula for the speed of waves?
400
two or more waves over lap and combine together
What is Interference?
400
the frequency of a sound as you perceive it
What is pitch?
400
A sound at frequencies higher than most people hear
What is ultrasound?
500
transverse, longitudinal, and surface
What are the three main types of mechanical waves?
500
the maximum displacement of the medium from its rest position
What is Amplitude?
500
a wave that appears to stay in one place
What is a Standing Wave?
500
a unit the compares the intensity of different sounds
What is a decible?
500
the response of a standing wave to another wave of the same frequency
What is resonance
