| Question | Answer |
|---|---|
| Energy | The ability to do work. |
| Mechanical Energy | Energy produced by a machine or moving part. |
| Light Energy | Electromagnetic energy that can be sensed by the eye. |
| Sound Energy | Mechanical energy that travels as waves through the air or water and vibrates the ear drum upon contact. |
| Electrical Energy | Energy resulting from the flow of charged particles. |
| Thermal/Heat Energy | Energy that can be measured by a thermometer. |
| Kinetic Energy | The energy of motion |
| Visible Spectrum | The portion of the electromagnetic spectrum that is visible to the human eye. |
| Potential energy | Stored energy. |
| Chemical energy | The energy that results during a chemical reaction |
| Joule | The standard measure of work or energy |
| Convex Lens | A convex lens is thicker at the center than at the edges.Rays of light that pass through the lens are brought closer together (they converge) |
| Concave Lens | Concave lenses are thinner at the middle. Rays of light that pass through the lens are spread out (they diverge). |
| Reflect | When light bounces off objects. |
| Refract | When light seems to bend as it passes through substances. |
| Prism | A glass or other transparent object with refracting surfaces that separates white light into a spectrum of colors. |
| Rainbow | An arch in the sky made up of different colors that forms when the sun's rays are refracted by rain drops, |
| Spectrum | The band of colors formed by a beam of light, like a rainbow. |
| Opaque | A material that does not allow light to pass through. |
| Translucent | A material that permits light to pass through but diffusing it so that objects on the opposite side are not clearly visible: |
| Transparent | A material that transmits rays of light through its substance so that bodies situated beyond or behind can be distinctly seen. |
| Absorb | The process by which one substance, such as a solid or liquid, takes up another substance. |
| Transmit | To send out or pass from one object to another or from one place to another. |
