WAVES
Study all about waves with this stack.
| Question | Answer |
|---|---|
| Frequency | The number of crests/troughs that pass by a given point per second. |
| Wavelength | The distance between two crests/troughs in a wave. |
| Transverse wave | A wave where the medium moves perpendicular to the direction of the wave. |
| Longitudinal Wave | A wave where the medium moves parallel to the direction of the wave. |
| Medium | Material in which a wave travels. |
| Mechanical Wave | A wave that is caused when energy causes a vibration thru a medium. |
| Electromagnetic Wave | A wave that does not travel through a medium and can travel through empty space. |
| Compression | The area in a longitudinal wave where the particles are close together. |
| Crest | The highest point of a transverse wave. |
| Energy | The ability to move or change an object, or what a wave carries. |
| Rarefaction | Area in a longitudinal wave in which the particles are spread out. |
| Trough | The lowest point of a transverse wave. |
| How does a particle in a surface wave move? | Circular |
| What is frequency measured in? | Hz (Hertz) |
| Period | The time between crests/troughs. |
| What is the formula to calculate wave speed? | Frequency * wavelength |
| What do ALL waves carry? | Energy |
| Reflection | Bouncing of wave as it hits a surface. |
| Refraction | Bending of waves as it moves through different substances. |
| Diffraction | The bending of waves around a barrier. |
| What are the two types of interference? | Constructive & Destructive. |
