Experimental procedure Click on the link below to the Optics Bench simulation 2 http://www.physicsclassroom.com/Physics ... tics-Bench By default, Optics Bench opens in Lens mode. Click on the Lens button to change to Mirror mode. You should observe a curved mirror with its principal axis, a candle, and three sets of incident and reflected rays as shown in the figure. Experiment with the environment in the following ways: • Tap and drag the candle back and forth along the axis; observe how the image changes. Use the focus slider to change the focal length. Notice how f and 2f change location. The 2f point is the Center of Curvature location. ● Use the height slider to change the image height. Notice how the object can be changed into an arrow or a vertical column of letters (A B C). ● Notice how the incident rays can be toggled ON and OFF. Notice how the object can be dragged to the right side of the mirror - the convex side. CONCAVE Mirror: 1. Ray diagrams for infinite object and image distances a) Rays coming from an object at infinity converge to form an image at the focal point. Construct a ray diagram with several rays parallel to and above the optic axis to show they converge at f. MIRROR
b) Using the Mirror equation, determine the image distance for an object at infinity. 2. Image locations for non-infinite object distances for different object locations a) Use the sliders to set the focal length of the mirror to approximately 30 cm and the object height to approximately 20 cm. b) Drag the OBJECT to the various locations described in Table 1. c) For each location, practice the L.O.S.T art of image description that is, describe the image Location, Orientation, Size, and Type. d) Record your observations using Table 1 for each case. e) Measure the object and image heights. Then calculate the magnification factor (m). f) Sketch a ray diagram (see box Ray Diagram below), of an object at a distance slightly beyond R (i.e., do > R) Tables and Data Analyses: Table 1- Concave Mirror L.O.S.T art of Image Description Object Position Orientation Size Type* do > R do=R f<do < R do=f do <f * Real images are formed when reflected light rays converge at the image location. Virtual images are formed when light rays diverge after reflection. CONVEX Mirror: 1. Use same values of focal length and object height. Location
2. Drag the object to the right side of the mirror and observe the image. The right side of the mirror is the convex side. 3. Do the basic characteristics of the image depend upon where on the right side of the mirror that the object is placed? Experiment to find out. 4. Practice the same L.O.S.T art of image description for a nearby and distant object position described in Table 2. Record your observations in Table 2 by entering the appropriate descriptor. 5. Sketch a ray diagram (see box Ray Diagram below), for an object at do <f, and draw conclusions about the characteristics of the image formed by a convex mirror.
