| Question | Answer |
|---|---|
| Bending of Light as it passes from one transparent material into another | Refraction |
| Bouncing of light waves off a surface | Reflection |
| Heat transfer from touching surfaces | Conduction |
| Heat transfer from a gas or liquid | Convection |
| Heat transfer from space | Radiation |
| Distance from the top of one wave to the top of another wave | Wavelength |
| The highness or lowness of a sound as determined by it's frequency | Pitch |
| The number of times a sound waves vibrates in 1 second | Frequency |
| The amount of energy in a sound wave | Amplitude |
| Bulging lens that brings light together | Convex |
| Lens that caves in and spreads light apart | Concave |
| These waves travel in straight rays | Light Waves |
| These waves travel in all directions | Sound Waves |
| An example of conduction | Cooking pancakes on a stove |
| An example of convection | Boiling noodles |
| An example of radiation | Cooking a hot dog in the microwave |
| Letting only some light through- objects appear blurry | Translucent |
| Letting all light through- objects seen clearly | Transparent |
| What is white light made of? | All colors |
| What separates white light? | Prism and Water |
| What color has the longest wavelength? | Red |
| What electromagnetic waves have the highest energy? | X-ray |

| What is an example of an insulator? | wood, |
| What is an example of translucent? | mt. Dew bottle, plastic |
| Why do we see the color red? | The color reflects off the object and absorbs all other colors. |
| Why does a pencil look bent in water? | The light bends in water because the water slows down the speed of light. |
