Unit 12 test Review
Unit 12 Waves
| Term | Definition |
|---|---|
| Sound waves | do carry energy |
| Mechanical waves | always need a medium through which to transport energy |
| The particles in a surface water wave | Move back and forth, in a circle and Up and Down |
| Transverse Waves | Waves in which the particle of medium move at right angles to the direction of the wave |
| Seisinic Waves | waves caused by an earthquake |
| Rarefaction | the troughs of a transverse wave correspond to the compressional wave |
| Trough | the lowest point on a transverse |
| Amplitude | wave that is measured from the crest of one wave to the crest of the next |
| If the wavelength of a given wave decreases, | you know that its frequency will increase |
| Two waves have the same frequency and wavelength, but the first wave has a greater amplitude. | The energy of the first wave is greater than that of the second |
| Hertz | The unit for frequency |
| Resonance | the ability of an object to vibrate by reflecting energy |
| Wave | Repeating disturbances that transfer energy through matter or space |
| Light is one type of wave that can travel through empty | energy |
| Transversal and compressional | two type of mechanical waves |
| Seisic | waves can travel through Earth and along Earth surface |
| Rarefaction | the area where the particles are farthest apart is a rarefaction |
| compression | the compressions in a compressional wave correspond |
| Wavelength | the symbol lambda |
| Transverse Waves | A line perpendicular to a reflecting surface |
| Refraction and Diffraction | involve the bending of waves |
| Water waves | transverse and compressional |
| Amplitude | The energy a wave carries is measured |
| Distractive interface | When the crest of one wave passes through the trough of another waves |
| Velocity | When a wave passes from a less dense medium, like air to a medium of greater density, like water |
| Wave A has greater frequency and wave B, but the amplitude of the two waves is the same. | The energy of wave A is EQUAL TO that of wave B |
| Reflection | The property of light that allows you to see yourself in a mirror. |
| When light passes from water into air | the light bends AWAY FROM the normal |
| When two sound waves are out of phase | The amplitude and loudness DECREASE |
| Waves | Repeating disturbance that transfer energy through matter or space |
| Energy | Light is one type of wave that can travel through empty space to transfer |
| destructive interference | When the crest of one wave passes through the tough of another wave |
