| Question | Answer |
| Medium | A physical environment in which phenomena occur |
| Mechanical Wave | A wave that requires a medium through which to travel |
| Electromagnetic Wave | A wave that consists of oscillating electric and magnetic fields, which radiate outward at the speed of light |
| Transverse Wave | A wave in which the particles of the medium move perpendicularly to the direction the wave is traveling |
| Longitudinal Wave | A wave in which particles of the medium vibrate parallel to the direction of wave motion |
| Crest | Highest point of a wave |
| Trough | Lowest point of a wave |
| Amplitude | The maximum distance that the particles of a wave's medium vibrate from their rest position |
| Wavelength | The distance from any point on a wave to an identical point of the next wave |
| Period | The time that it takes a complete cycle or wave oscillation to occur |
| Frequency | The number of waves produced in a given amount of time |
| Doppler Effect | An observed change in the frequency of a wave when the source or observer is moving |
| Reflection | The bouncing back of a ray of light, sound, or heat when the ray hits a surface that it doesn't go through |
| Diffraction | A change in the direction of a wave when the wave finds an obstacle or an edge, such as an opening |
| Refraction | The bending of a wave front as the wave front passes between two substances in which the speed of the wave differs |
| Interference | The combination of two or more waves that results in a single wave |
| Constructive Interference | A superposition of two or more waves that produces an intensity equal to the sum of the intensities of the individual waves |
| Destructive Interference | A superposition of two or more waves that produces an intensity equal to the difference of the intensities of the individual waves |
| Wave | A disturbance that carries energy through matter or space |
