Mirrors, Lenses and Image Formation I. Go to the following website: Concave and Convex Mirrors 2. Figure ] shows an example of what you should see on your screen. Name: Date: Concave and Convex Mirrors Concave Mirror: 2f > do > f Ray Tracing for Mirrors Image Characteristics do = 6.69 di = 9.96 Inverted ho = 1.8 hi = -2.69 Real Image hi > ho di > 2f 1. Is the diagram above a Concave or a Convex Mirror? 2. Which color is the Ray 1 in the ray diagram? Figure 1: Initial Configuration after opening the Concave and Convex Mirrors Simulator 3. Which color is the Ray 3 in the ray diagram? 3. Click on the top of the Object arrow. . Move Up or down to adjust the object height, ho. . Move Left or Right to adjust the object distance, do. . For purposes of this lab, each grid square is 1 cm height and 1 cm wide. . Place the Object arrow Left of the Mirror for a Concave Mirror. Image . Place the Object arrow Right of the Mirror for a Convex Mirror. 1. Is the diagram above a Concave or a Convex Mirror? 2. Which color is the Ray 2 in the ray diagram? 3. Based on the location of the object, is the Image Type: Real or Virtual? 4. Is the Image Orientation: Upright or Inverted?Convex Lens - (Converging) Concave Lens - (Diverging) 1. Place the object to the left of the lens at -7 cm. 1. Place the Focus' to the right of the lens near 4.0 cm to switch to a concave lens. 2. Click on the Object arrow and set the height, to 3 cm. 2. Place the object to the left of the lens at -7 cm. 3. Get the object distance, do. Record. 3. Click on the Object arrow and set the height, to 3 cm. 4. Get the image distance, di. Record. 4. Get the object distance, do. Record. 5. Get the object height, ho. Record. 5. Get the image distance, di. Record. 6. Get the image height, hi- Record. 6. Get the object height, ho. Record. 7. Record the Image Type (Real or Virtual): 7. Get the image height, hi- Record. . Record the Image Orientation (Upright or Inverted): Type (Real or Virtual): 9. Place the object to the left of the lens at -12 cm. 8. Record the Image Orientation (Upright or Inverted): 10. Repeat Steps 3-7. 9. Place the object to the left of the lens at -12 cm.

Make sure you pay attention to significant digits for the given input parameters and the results you calculate. 1. An object is 4.30 cm high and is placed 12.6 cm to the left of a concave mirror. The mirror has a radius of curvature of 6.20 cm. Locate and describe the image. (a) Is the Image Type: Real or Virtual? (b) How far is the image from the mirror? (c) Is the Image Orientation: Upright or Inverted? (d) How tall is the image ? 2. An object is 5.50 cm high and is placed 3.30 cm to the left of a convex mirror. The mirror has a radius of curvature of 5.20 cm. Locate and describe the image. 3. Is the Image Type: Real or Virtual? 4. How far is the image from the mirror? 5. Is the Image Orientation: Upright or Inverted? 6. How tall is the image
