Question | Answer |
Wave | Disturbance that transfers energy from place to place |
Energy | The ability to do work |
Medium | Material through which a wave travels |
Mechanical Wave | Need a medium through which to travel |
Vibration | Repeated back and forth, or up and down motion |
Transverse Wave | Move the medium at right angles to the direction in which the wave travels |
Crest | High point of a transverse wave |
Trough | Low part of a transverse wave |
Longitude Wave | move the medium parallel to the direction in which the waves travel |
Compression | Parts where the coils are close together |
Rarefaction | Parts where the coils are spread out |
Amplitude | the maximum distance that the particles of the medium carrying the wave move away from their rest position |
Wavelength | The distance between two corresponding parts pf a wave |
Frequency | The number of complete waves that pass a certain point in a certain amount of time |
Hertz (Hz) | Units frequency is measured in |
Reflection | Interaction with a surface |
Law of Reflection | States that the angle of incidence equals the angle of reflection |
Refraction | Bending of waves due to a change in speed |
Diffraction | When a wave moves around a barrier or through an opening in a barrier, it bends and spreads out |
Interference | The interactions that between waves that meet |
Constructive Interference | The interference that occurs when waves combine to make a wave with a larger amplitude |
Destructive Interference | The interference that occurs when two waves combine to make a wave with smaller amplitude |
Standing Wave | A wave that appears to stand in one place, even though it's really two waves interfering as they pass each other |
