This is a collection of physics facts about spherical mirrors and thin lens approximations. The distance between the object and optical piece is the variable "p." The distance between the image and the optical piece is the variable "q."

| 773497533 | What does a concave lens look like. | It looks like this. |  |
| 773497534 | What does a convex mirror look like? | It looks like this |  |
| 773497535 | What does a "positive" lens look like? | These lenses are wider in the middle that at the edges. |  |
| 773497536 | What does a "negative" lens look like | These lenses are thinner in the middle that at the edges. |  |
| 773497537 | What does a converging lens look like? | These lenses are wider in the middle that at the edges. | |
| 773497538 | What does a diverging lens look like | These lenses are thinner in the middle that at the edges. | |
| 773497539 | Where can an object be placed in front a concave mirror such that it creates a real image that is the same height as the original? | At the center of curvature. | |
| 773497540 | Where can an object be placed in front of concave mirror such that it creates a real image? |  | |
| 773497541 | Where can an object be placed in front of concave mirror such that the image it creates is magnified larger than the original? | Any between the focus and the mirror's surface will create this kind of image magnification. | |
| 773497542 | This type of mirror cannot enlarge an object. | Convex mirror give this type of magnification. | |
| 773497543 | What is the sign of the calculated magnification for the image to be upside-down. | A negative magnification means it is upside down. | |
| 773497544 | What is the sign of the calculated magnification for the image to be erect. | A positive magnification does this to the image. | |
| 773497545 | When playing hide-and-go-seek, where is the perfect place to stand to hide your image from a concave mirror? | At the focus because an image is not created when standing at the focus. | |
| 773497546 | What is the sign of "q" for an image to be a virtual image? | Negative "q's" yield virtual images. | |
| 773497547 | Which mirror can only generate virtual images? | Convex mirrors can only generate these image types. | |
| 773497548 | What type of mirror can only generate upright images? | Convex mirrors. | |
| 773497549 | Which incident ray of light on a curved mirror is reflected at the same angle it hits the mirror? | The ray that impacts the mirror at the vertex. | |
| 773497550 | Which incident ray of light on a curved mirror is reflected back on itself? | The incident ray that travels through the center. | |
| 773497551 | Which incident ray of light on a THIN lens is not refracted? | The one that travels through the vertex of the lens. | |
| 773497552 | What type of lens cannot magnify an image? | Diverging lenses cannot magnify a object's image. | |
| 773497553 | What type of lens can only create virtual images? | Diverging lenses can only create virtual images. | |

| 773497557 | Where is a real image located on any mirror? |  | |
| 773497558 | Where is a real image located when using any lens? |  | |
| 773497559 | Where is a virtual image located when using any lens? |  | |
| 773497560 | Which type of lens has a negative focal length? (Do not answer a negative lens) | Diverging lenses have a negative focal length. | |
| 773497561 | Which type of lens has a positive focal length? (Do not answer a positive lens.) | Converging lenses have a positive focal length. | |
| 773497562 | Which type of lens has cannot magnify an object? | Diverging or negative lenses cannot magnify and object. | |
| 773497563 | If an object is placed at the center of curvature for a converging lens, then where will the image be found? |  | |
| 773497564 | Where can an object be placed in front of a positive lens such that the image will have the same height as the object. | At the center of curvature. | |
| 773497565 | If light is shining on a converging lens from left to right, --->, then which side will have the primary focus? | The primary side is the side the light 1st hits. The primary focus is the focus associated with the side the light hits first. |  |
| 773497566 | If light is shining on a diverging lens from left to right, --->, then which side will have the primary focus? | The primary side is the side the light hits first. The primary focus is the focus associated with the side the light hits first. |  |
| 773497567 | Besides being on the back side of a mirror, what to all virtual images have in common? | All virtual images are erect, (upright.) | |
| 773497568 | Which type of lens cannot magnify an object? | Diverging, or negative, lenses canot magnify an object. | |
| 773497569 | What units are the variables in the lens equation? | It does not matter as long as they are all the same. | |
| 773497570 | What are the units used in calculating the magnification of an image? | It does not matter as long as they are all the same. | |
| 773497571 | When is the distance between a mirror and object negative in a formula? | Never. Object distances are all positive. |
