23.1    Two plane mirrors stand facing each other, 2.84 m apart, and a woman stands between them. The woman faces one of the mirrors from a distance of 1.15 m and holds her left arm out to the side of her body with the palm of her left hand facing the closer mirror. What is the apparent position of the closest image of her left hand, measured perpendicularly from the surface of the mirror in front of her? m behind the nearer mirror What is the position of the next image? m behind the nearer mirror What is the position of the third closest image? m behind the nearer mirror

F1 F2 Figure above shows a thin converging lens in front of a concave spherical mirror with the radius of curvature R = 5.0cm. Assume that the lens focal points F1 and F2 are 5.0 cm from the center of the lens. The lens and mirror are 18.0 cm apart, and an object is placed 7.0cm to the left of the lens. How far from the lens is the position of the final image? State your answer in cm to the nearest 0.1 cm.

Suppose you have a concave mirror as shown in the image below. If h = 1.84m is the height of an object (really the displacement of the top of the object from the axis) and h' = 4.21m is the height of the image, what is the magnitude of the transverse magnification (in units of meters)? Image Object

Part A

In the figure below, a diverging lens and concave spherical mirror are positioned along an optical axis, with an object half way between the two. The distance between the lens and mirror is d = 23.6 cm. The magnitude of the mirror's radius of curvature is 20.1 cm, and the lens has a focal length of flens = -19.0 cm. Lens Object Mirror (a) Considering only the light that leaves the object and travels first toward the mirror, locate the final image formed by this system. (Give the magnitude of the image distance in cm, and select its location with respect to the lens.) image distance image location -Select--- (b) Is this image real or virtual? O real O virtual (c) Is it upright or inverted? O upright O inverted (d) What is the overall magnification? cm

A 1.8-m-tall man stands 2.0 m in front of a vertical plane mirror. 1)How tall will the image of the man be? (Express your answer to two significant figures.)

Two mirrors make an angle of 120° with each other as shown in the Figure below. A ray is incident on Mirror M1 at an angle of 65° to the normal. Find the angle the ray makes with the 2. normal to M2 after it is reflected from both mirrors. Bret Bune ef ine = 65° 120 M1
