| Light waves can travel through empty space without needing a solid, liquid, or gas | Medium |
| Rays of light passes through a ________ object with almost no disturbance. | Transparent |
| Some rays of light pass through a ________ object, and some light rays are blocked or bent in different directions. | Translucent |
| Rays of light are reflected or absorbed by an ______ object. | Opaque |
| Light rays that bounce off a _____ can form an image of an object. | Mirror |
| If you raise your left hand in front of a mirror, in your ______ it appears that your ______ hand is raised. | Reflection Right |
| When light rays strike a dull or a rough surface, they do not form an | Image |
| Concave mirrors cave in word, convex mirrors curved outward, and _____ mirrors are flat. | Plane |
| The type of mirror that is used to gather light inside a telescope is the _____ mirror. | Concave |
| The change in direction of a wave, called _____, is caused by a change in speed as the wave moves from one medium to another. | Refraction |
| An image that is formed by a concave lens is always _____________ and smaller than the actual object. | Right-side-up |
| A ______ telescope uses to convex lenses to form an image while a _____ telescope uses a concave mirror to form an image. | Convex-Refracting Concave-Reflecting |
| If your eye shape is even slightly off, your vision may be | Impaired |
| Nearsightedness causes light rays from distant objects to be focused in front of the | Retina |
| How do you sunglasses work to protect your eyes? | Dark sunglasses are translucent, so they block or bend some of the light before it passes through to your eyes; The polished surfaces, especially if they are mirrored, reflect some of the light away from your eyes. |

| Describes objects that do not allow any light to pass through them | Opaque |
| Describes objects that allows some light to pass through them | Translucent |
| Law that states that the angle between an incoming light ray in a surface is equal to the angle between the reflected light ray and the surface | Law of reflection |
| Describes objects that allow light to pass through them with almost no disturbance | Transparent |
| A piece of transparent material with at least one curved surface | Lens |
| An object with a polished surface that forms reflected images | Mirror |
| When an object let’s light pass right through it, the object is described as | Transparent |
| When an object lets sunlight through but also blocks or bends some of the light away, it is described as | Translucent |
| Objects that do not allow any light to pass through them are described as | Opaque |
| An object with a polished surface that forms reflected images is called a | Mirror |
| When light hits a dull or rough surface, it may still ______, but it will not form an image. | Reflect |
| When light passes through a _____ lens, the light rays are refracted TOGETHER. | Concvex |
| When light passes through a _____ lens, the light rays are refracted APART. | Concave |
| Light rays entering the eye are supposed to focus on the | Retina |
