William Welke- Waves
all the things that characterise a wave
| Answer | Question |
|---|---|
| Crest | The highest displacement of an wave |
| Transverse | curvy wave with right angles |
| Longitudinal | Straight wave with compressions and refractions |
| Trough | The lowest displacement of an wave |
| Amplitude | the mesurement of displacement- from crest/trough to starting line |
| Reflection | Waves bouncing off a medium, loosing some energy |
| Destructive interference | when two waves cancel each other |
| interferance | when a wave is made or when two wave collide |
| constructive interferance | When two waves collide and get louder |
| Wavelength | The Point where the wave repeats itself |
| Hertzs | Frequency is measured in... |
| medium | What sound waves travel through |
| Refraction | When a wave changes because the speed it can travel through an object changes |
| Difraction | When a wave changes because of a barrier or corner |
| wave | a disturbance in energy |
| Mechanical energy is created when... | Energy causes medium to move |
| Hertz | Wavelength times ____ = velocity |
| mechanical waves are classified by... | how it moves |
| Why can you see the explosion before you feel the shockwave | light is faster than sound |
| Mechanical waves travel through a medium by... | energy from particle to particle |
| ressonanance | occurs when vibrations traveling through an object match the object’s natural frequency |
