| Question | Answer |
|---|---|
| A disturbance that transmits energy through matter or space | Wave |
| The matter through which a wave travels | Medium |
| A wave that requires a medium through which to travel. Ex- Sound waves use air as a medium | Mechanical Wave |
| A wave that does not require a medium through which to travel Ex- Light travels through space where there is no medium | Electromagnetic Wave |
| A wave that vibrates parallel to the direction that the waves travel Ex- A sound wave, a wave produced by a spring | Longitudinal Wave |
| A wave that vibrates perpendicular to the direction that the wave travels. Ex- A light wave, a wave produced by rope | Transverse Wave |
| The highest point of a transverse wave | Crest |
| The lowest point of a transverse wave | Trough |
| A wave that vibrates perpendicular to the direction that the wave travels. Ex- A light wave, a wave produced by rope | Transverse Wave |
| The highest point of a transverse wave | Crest |
| The lowest point of a transverse wave | Trough |
| The greatest distance that particles in a medium move when a wave passes. | Amplitude |
| The distance between two successive parts of a wave | Wavelength |
| When two or more waves are traveling along a medium meet in the same place at the same time, they combine to form a new wave | Principle of Superposition |
| The number of wavelengths that pass a given point in a second time interval | Frequency |
| The time required for one full wavelength to pass a given point =l/T | Period |
| When two or more waves are traveling along a medium meet in the same place at the same time, they combine to form a new wave | Principle of Superposition |
| When two waves with equal but opposite amplitudes meet, the displacement of the medium at each point in the overlap is reduced. | Destructive Interference |
| When two waves with amplitudes in the same direction meet, the displacement of the medium is increased | Constructive Interference |
| The bending of a wave as it moves around an obstacle or passes through a narrow opening | Diffraction |
| When a wave strikes a surface that it cannot pass through, it bounces off the surface at the same angle that it strikes the surface with | Reflection |
| When a wave strikes a boundary and enters a boundary and enters into a different medium where its velocity changes, the transmitted wave moves at a different angle than the incident wave | Refraction |
