A candle is placed in front of a convex mirror.

Part A. Consider the following diagrams noting that the scale is different between diagrams. In these diagrams, C and F represent the center of curvature and the focal point of the convex mirror, respectively. The image formed by the mirror is obtained using the ray-tracing technique. Which diagram(s) are correct? (Type A if you think that only diagram A is correct, type AB if you think that only diagrams A and B are correct, and so on).

 

Part B. If the radius of curvature of the convex mirror is , at what distance from the mirror must the candle be placed so that its image is formed   from the mirror? (Express your answer in centimeters.)

Part C. Consider the following diagrams, where now C and F represent, respectively, the center of curvature and the focal point of the concave mirror. Again, the image formed by the mirror is found by ray tracing. Choose the correct diagram(s). (Type A if you think that only diagram A is correct, type AB if you think that only diagrams A and B are correct, and so on.)

 

Part D. Assuming that the candle remains at a distance from the mirror (the same distance found in Part B), at what distance from the mirror will its image form now? (Express your answer in centimeters.)

Figure6 of 6The figure labeled C shows two rays coming out of the top of the object in front of the concave mirror, forming an acute angle with the axis. Upper ray reflects parallel to the axis. And the lower ray reflects in the direction exactly opposite to its initial direction. There is a focus point F on the axis in front of the mirror and a center of the mirror’s curvature C between point F and the object. The image is smaller, than the object, located between points F and C, and inverted, its tip is formed by intersection of the reflected rays. The initial upper ray passes through point F and the initial upper ray passes through point C.

Part A Consider the following diagrams noting that the scale is different between diagrams. In these diagrams, C and F represent the center of curvature and the focal point of the convex mirror, respectively. The image formed by the mirror is obtained using the ray tracing technique. Which diagram(s) are correct?(Figure 1) (Figure 2) (Figure 3) Type A if you think that only diagram A is correct, type AB if you think that only diagrams A and B are correct, and so on.

Part B If the radius of curvature of the convex mirror is 50.0 cm , at what distance do from the mirror must the candle be placed so that its image is formed 20 cm from the mirror? Express your answer in centimeters. View Available Hint(s) dod o d_o = cm The convex mirror is now replaced by a concave mirror with the same radius of curvature.

Part C Consider the following diagrams, where now C and F represent, respectively, the center of curvature and the focal point of the concave mirror. Again, the image formed by the mirror is found by ray tracing.

Part D Assuming that the candle remains at a distance do from the mirror (the same distance found in Part B), at what distance di from the mirror will its image form now? Express your answer in centimeters. View Available Hint(s) did i d_i = nothing cm

The figure labeled A shows two rays coming out of the top of the object, one parallel to the axis of the mirror, and the other at an acute angle with the axis. The parallel to the axis ray reflects upper, than its initial way was, and the other ray reflects parallel to the axis. Prolongations of the reflected rays and the lower initial ray are shown beyond the mirror. There is a focus point F on the axis behind the mirror and the center C of the mirrorâs curvature. An image is smaller, than the object, and is located closer than the focus point F and its tip is an intersection of the prolongations of the upper reflected ray and lower initial ray. The prolongation of the reflected rays run through point F for the upper ray and through point C for the lower ray.

A 4.5-cm tall object is placed 26 cm in front of a sphericalmirror. You want to produce a virtual image that is upright and 3.5cm tall.

(a) What type of mirror (convex or concave) should be used?
(b) Where is the image located?
(c) What is the focal length of the mirror?
(d) What is the radius o f curvature of the mirror?


1. Geometrical Optics: A candle is at the center of curvature of aconcave mirror with focal length of fm= 10 cm. A divergingent lenshas a focal length of f1= 20 cm and is 60 cm to the right of thecandle. The lens forms two images of the candle. The first isformed by light passing directly through the lens. The second imageis formed from the light that goes from the candle to the mirror,isreflected, and then passes through the lens.

A. Use ray tracing techniques on the diagram above to determinethe approximate position ofeach image.

B. Determine the location of each of the images with respect tothe mirror.

C. Are they real or virtual? (give your answers for each of theimages).

Image1: REAL or VIRTUAL

Image2: REAL or VIRTUALD.

Are they upright or inverted?

Image1: UPRIGHT or INVERTED

Image2: UPRIGHT or INVERTEDE.

If the candle height is 5 cm what will be the height of theimages
