Card: 1 / 40 |
|
|
Regular reflection |
Card: 2 / 40 |
|
|
Riddle: I can give you a reflection, but I am not alive. What am I? |
Card: 3 / 40 |
|
|
A mirror |
Card: 4 / 40 |
|
|
True or False: Lateral inversion means the top and bottom of an image are reversed. |
Card: 5 / 40 |

Riddle: I make things look larger, but I'm not a lens. What am I? |
Card: 13 / 40 |
|
|
A concave mirror |
Card: 14 / 40 |
|
|
True or False: Spherical mirrors can only be concave. |
Card: 15 / 40 |
|
|
False. There are both concave and convex mirrors. |
Card: 16 / 40 |

What happens to light rays when they reflect off a concave mirror? |
Card: 23 / 40 |
|
|
They converge at a point. |
Card: 24 / 40 |
|
|
Riddle: I show you a reflection, but I do not change size. What am I? |
Card: 25 / 40 |
|
|
A plane mirror |
Card: 26 / 40 |
|
|
Fill in the blank: A mirror that forms an inverted image when the object is beyond the center of curvature is called a ______ mirror. |
Card: 27 / 40 |
|
|
Concave |
Card: 28 / 40 |
|
|
What property do all images formed by plane mirrors share? |
Card: 29 / 40 |
|
|
They are virtual and laterally inverted. |
Card: 30 / 40 |
|
|
True or False: The image formed by a convex mirror is always real and inverted. |
Card: 31 / 40 |
|
|
False. The image formed by a convex mirror is always virtual and upright. |
Card: 32 / 40 |
|
|
What is the normal in the context of reflection? |
Card: 33 / 40 |
|
|
A perpendicular line drawn to the surface at the point of incidence. |
Card: 34 / 40 |
|
|
Which formula relates object distance (u), image distance (v), and focal length (f) for spherical mirrors? |
Card: 35 / 40 |
|
|
1/f = 1/u + 1/v |
Card: 36 / 40 |
|
|
