CH‐34‐A‐2: A concave shaving mirror has a radius of curvature of +28.5 cm. It is positioned so that the (upright) image of a manʹs face is 1.76 times the size of the face. How far is the mirror from the face? Show all work CH‐34‐A‐3: Consider the object‐concave mirror system shown. (a) Label the focal point with an F, the radius of curvature with C, and the object with O. (b) Draw the ray diagram (at least 3 rays) for light originating at the tip of the object. (c) Draw the image. (d) If the distance from the object to the mirror is 7 m and the radius of curvature is 4 m, find the distance from the image to the mirror. Is the image real or virtual, upright or inverted, bigger or small (and by how much)? Show all work CH‐34‐A‐4: As shown in the sketch at the right, an object (arrow) is placed 25.0 cm in front of a spherical,
convex mirror with a radius of curvature of 50.0 cm. (a) Is the image real or virtual, upright or inverted? (b) What is the relative size of the arrow? Show all work
