Light
| Term | Definition |
|---|---|
| energy | Light is a form of ___________________. |
| transverse | Light travels in_______________________ waves. |
| straight | Light travels in _________________ paths called rays and do not need a medium (solid, liquid, or gas) through which to move. |
| ray | the straight line that represents the path of light |
| wavelength | the distance between two consecutive waves, usually measured crest-to-crest or trough-to-trough |
| crest | the highest point on a wave |
| trough | a valley between two waves or the lowest point of a wave |
| frequency | the number of waves passing a given point in one second |
| visible light | Within the electromagnetic spectrum, the area that we see as light is known as "_____________________" or "white light". |
| red | Of the visible light, ________ would have the longest wavelength. |
| violet | __________________ has the shortest wavelength |
| ROY G BIV | Acronym to remember order of visible light: |
| refract | Light can be bent or _______________. |
| Smooth and hard | ____________________________________________ objects are better at reflecting light than other objects. |
| rough | When light bounces off a __________________ surface, it is scattered in many directions |
| angle | The Law of Reflection states that when light hits a surface, the _______________ at which it is reflected (bounces off) is the same as the angle at which it strikes. |
| color | The _______________________ of an object is the color of the light it reflects. |
| Black | ____________________ is when a material absorbs all of the visible light and no light is reflected back. |
| White | _____________ is a reflection of all visible light together. |
| prism | A _____________ can be used to refract white/visible light. |
| bent | When the different wavelengths of light in white light pass through a prism, they are ____________________ at different angles (refracted). |
