Our homework due today was to find the definitions of the words ray-concave lens. If somebody didn't get all the words then here they are.
Ray: Straight lines of light waves (shown as an arrow)
Regular Reflection: When parallel waves of light hit a flat surface
Diffuse Reflection: When parallel waves of light hit a bumpy surface
Plane Mirror: A flat sheet of glass with a smooth, silvercolored coating on one side
Image: A copy of an object formed by reflected or refracted rays of light
Virtual Image: Upright image that forms where light seems to come from (see in place mirror)
Concave Mirror: Mirror with a flat surface that curves inward
Convex Mirror: Mirror with a flat surface that curves outward
Focal Point: The point which rays parallel to the optical axis meet
Mirage: An image of a distant object caused by the refraction of light.
Lens: A curved piece of glass or other transparent material that is used to refract light.
Convex Lens: A lens that is thicker in the center than at the edges.
Concave Lens: A lens that is thinner in the center than at the edges.
At the end of class, Ms.D gave us all a lab handout that we're going to work on on Monday. It is our homework to read it so that we have an idea of what to do on monday with our 11 o'clock partners. The lab is called Light Behaviors, and we're going to be playing with Mirrors, Lenses, and Prisms.
Next scribe is (drum roll): Lara
