A model that represents light as a straight line, or ray, indicating the path of a beam of light. What is the ray model of light? Row 1, Col 1

Regular mirror in the bathroom, one smooth surface. What does a plane mirror look like? 1, 2

A curved piece of transparent material that refracts light by converging or diverging it. What are lens? 1, 3

The angle of incidence equals the angle of reflection. State the Law of Reflection. 1, 4

Incident Ray What is the incoming ray called? 2, 1

It is where parallel rays of light meet at a single point when reflected off of a concave mirror. What is a focal point? 2, 2

They diverge rays of light. What does concave lenses do to rays of light? 2, 3

Different temperatures of air. Cooler air is denser than warmer air. How are mirages produced? 2, 4

The bending or changing direction of a wave as it passes from one material to another. What is refraction? 3, 1

Convex mirror What type of mirror diverges rays of light? 3, 2

They converge rays of light to a focal point. What does convex lenses do to rays of light? 3, 3

Smooth = uniformly, all the same. Rough = all different directions, random. How do rays of light reflect off of smooth and rough surfaces? 3, 4

Transparent = material that allows light rays to pass through freely. Translucent = most rays get through, but are scattered in all directions and some are completely blocked. Opaque = prevents light rays from going through, completely blocked. Describe the following: -Transparent -Translucent -Opaque 4, 1

Concave mirrors What type of mirror converges rays of light? 4, 2

Smaller and upright. What type of image does a concave lens make? 4, 3

Convex mirrors What type of mirror is used in car? 4, 4

Can be predicted by the ray model of light. Objects block the rays so depending on where the light source is and where the object is determines the shadow. Describe how shadows are made? 5, 1

Plane = Exact image, same orientation Concave = Depends on where the object is to the focal point, can be small, large, inverted and upright. Convex = Smaller image and see more objects. What does the image look like when reflected off of the following mirrors: - Plane - Concave - Convex 5, 2

The image gets bigger, but it is still inverted (upside down). What happens to an image when the object goes from really far away to between two and one focal lengths in front of a convex lens? 5, 3

An image appears to be larger and the same orientation. What happens to an image when the object goes from the focal point to closer than one focal length in front of a convex lens? 5, 4
