Textbook Reference 10.3 (P.419-430). Learning Goals. Understand how to draw ray diagrams for concave mirrors. Be able to identify when images are real or virtual. Success Criteria. To draw at least one ray diagram for concave mirrors and to identify if the image is real or virtual.. Unit 3:Light. Curved mirrors. Terms:. Curved mirror- can be thought of as a large number of plane mirrors all having slightly different angles. The laws of reflection still apply. Converging mirror- has a concave reflecting surface. The most common type of curved mirror is a spherical mirror. A spherical mirror has the shape of a section from the surface of a sphere. Curved Mirrors. Concave mirror – the inside surface of the mirror is polished. On The Shelf. We’re studying lessons from. James to Christians which. have been scattered.. Thesis :. Christians must seek out .

Often we want to image (and measure) the location of different color proteins inside cells. XY registration is easy, but it is not so simple in Z.. point the brighter the point. The more lights you turn on the brighter the reflected light from objects in the room. See rays at right. Intensity proportional to |E|. 2. Light. source 2. Light. source 1. . But not ideal!

Are highly energetic radiations which are emitted when energetic electrons are made to incident on a metallic target.. Were discovered by German Physicist W.C. Roentgen in1895..
