100
What is energy?
The ability to do work.
100
What is a mechanical wave?
Waves that require a medium.
100
What is frequency?
How often a wave occurs in a give time period.
100
What is reflection?
The interaction with the surface of a wave.
100
What is standing wave?
A wave that appears to stand in one place, even though two waves interfering as they pass through each other.
200
What is a medium?
The material through which a wave travels.
200
What is a transverse wave?
A wave that vibrates the medium at a right angle.
200
What is wavelength?
The distance between two corresponding parts of a wave (crest to crest OR trough to trough).
200
What is refraction?
The bending of waves due to the change in speed.
200
What is a node?
These are always evenly spaced along a wave.
300
What is a mechanical wave?
This type of wave requires a medium.
300
What is crest/trough.
The top/bottom portions of waves.
300
What is speed?
How far the wave travels in a given amount of time.
300
What is diffraction?
When a wave moves around a barrier or through an opening in a barrier, it bends and spreads out.
300
What are antinodes?
Points of maximum amplitude on a standing wave.
400
What is a wave?
A disturbance involving the transfer of energy from place to place.
400
What is a longitudinal wave.
Vibrates the medium in the same direction in which the wave travels.
400
What is amplitude?
The height of a wave's crest from the resting position.
400
What is destructive interference?
Interference in which two waves combine to form a wave with a smaller amplitude than either original wave.
400
What is resonance?
An increase in the amplitude of a vibration that occurs when external vibrations match an objects natural frequency.
500
What is a vibration?
A repeated back and forth motion.
500
What is a surface wave?
When longitudinal and transverse waves combine.
500
What is a hertz (Hz)?
Frequency is measured in this unit of measurement.
500
What is constructive interference?
Interference in which a waves combine to form a wave with a larger amplitude than any individual waves amplitude.
500
What is energy in terms of waves?
This is transmitted by waves.
