CM-1 An object is placed 15.0 cm from a concave mirror with a focal length of 25.0 cm. a) Draw a diagram, showing 3 rays originating from the object reflecting off the mirror, and where they converge to form the image. b) What is the image distance? c) What is the total lateral magnification of the image? d) Is the image real or virtual? e) Is the image upright or inverted?

A man holds a double-sided spherical mirror so that he is looking directly into its convex surface, 44 cm from his face. The magnification of the image of his face is +0.29. What will be the image distance when he reverses the mirror (looking into its concave surface), maintaining the same distance between the mirror and his face? Be sure to include the algebraic sign (+ or -) with your answer. Number i Units

B. CONVERGING LENSES: After performing this activity, the students should be able to: Sketch the location of the image in the concave mirror, measure the distance and the height of the image, and describe the object and the image in every case. MATERIALS: Rufer PROCEDURES 2 Construct the image of the following, given the focal length, distance of the object (do) (f) and height of the object (ho) in centimeters. Describe the location of both the object and the image being constructed. Determine the exact distance and the height of the image. identify the case number of each. Complete the table below. NOTE: Arrows that represent the secondary axes should be in red color, arrow that represent the object and the image is in blue color as well as the line that shows the bending of light ray, the rest of the construction is in black color. That is why you will be needing 3 colored ballpen for this activity. Use another sheet of bond paper for your construction. Use accurate maeasure. three…

1. You are standing 2 m in front of your plane bathroom mirror which hangs on the wall. How far away is your image from you? A. 2 m B. 4 m C. 1 m D. Infinitely far away   2. An object is placed to the left of a lens. If the image of the object is formed on the right side of the lens, which of the following statements must be true?    A. The image is upright and the lens must be concave B. The image is inverted and real, and the lens must be convex C. The image is upright and virtual D. The image is upright, and the lens must be convex E. The lens could be concave or convex

A concave mirror produces a virtual image that is three times as tall as the object. Part A If the object is 12 cm in front of the mirror, what is the image distance? Express your answer using two significant figures. ΑΣφ ? di = cm Submit Request Answer Part B What is the focal length of this mirror? Express your answer using two significant figures. nν ΑΣφ ? cm Submit Request Answer

Choose true or false for each statement regarding the sign conventions for mirrors.  a)  Virtual images appear appear behind a mirror and have a negative value for the image distance.   b) The focal length f is positive for convex mirrors.  c)Real images appear in front of a mirror and have a negative value for the image distance.

A concave mirror has a focal length of 20 cm. Knowing that the image was placed 12 cm from the mirror: 10 a) What is the position (in cm) of resulting image? b) Draw a ray diagram to locate the image c) Describe the formed image.

c) Down d) South e) Up 13. An object located 70.0 cm from a concave mirror forms a real image 38.0 cm from the mirror. The mirror is then turned around so that its convex side faces the object. The mirror is moved so that the image is now 18.0 cm behind the mirror. How far was the mirror moved? a) 80.4 cm toward the object. b) 66.9 cm away from the object c) 3.13 cm away from the object d) 66.9 cm toward the object e) 3.13 cm toward the object.
