Round 1
A measure of how high or low a sound is that is based on the frequency of the sound wave.
What is pitch?
The lowest point on a transverse wave.
What is the trough?
The highest point on a transverse wave.
What is the crest?
The matter through which a wave travels.
What is a medium?
A disturbance that travels away from its source and transfers energy through space.
What is a wave?
A wave that transfers energy through a medium by making its particles vibrate.
What is a mechanical wave?
A mechanical wave in which the particles of the medium vibrate in the direction parallel to the direction of motion of the wave.
What is a longitudinal wave?
The combining of two or more waves, producing a new wave pattern.
What is interference?
The number of times per second that a wave vibrates or its adjacent matching points pass a certain point.
What is frequency?
A temporary change in normal conditions due to a transfer of energy.
What is a disturbance?
The maximum distance from a rest position, that the particles of a medium move, as they vibrate when a wave passes.
What is amplitude?
The distance between two adjacent corresponding points along a wave.
What is wavelength?
Particles in a transverse wave move in this direction
What is perpendicular?
Particles in a longitudinal wave move in this direction
What is parallel?
Sounds waves are an example of this type of wave.
What is longitudinal?
A wave in which the particles of the medium vibrate in a direction perpendicular to the direction of motion of the wave.
What is a transverse wave?
The different pitches you hear on guitar strings are because of this
What is frequency?
Periodic and repeating motion about a fixed point
What is vibration?
A rubber duck hitting the surface of water is an example of this
What is disturbance?
Sound does not travel in space because it lacks this
What is a medium?
Waves created by seismic activity pass through this medium
What is rock?
True or False: Particles in an ocean wave, near the point of disturbance, are the same particles that reach the shoreline.
What is false?
To find the wavelength of a wave, you measure this distance
What is between two adjacent crests or two adjacent troughs?
The midpoint between a wave's crest and its trough is called this
What is the rest position?
