| Question | Answer |
|---|---|
| real | can be projected on a screen |
| real (inverted or upright?) | inverted |
| virtual | cannot be projected on a screen |
| virtual (inverted or upright?) | upright |
| upright | the top of the image represents the top of the object |
| inverted | the top of the image represents the bottom of the object |
| smaller | the image is shorter than the object |
| same size | the image and object have the same height |
| larger | the image is taller than the object |
| concave | bows in in the center |
| convex | bows out in the center |
| image | forms where the light rays cross |
| diverge | move apart |
| converge | move toward, to come together |
| plane | flat |
| normal line | imaginary line drawn 90° from reflective or refractive surface |
| measure angles compared to this | normal line |
| reflection | angle i = angle r |
| refraction | angle i ≠ angle r |
