A spherical mirror is to be used to form an image 4.50 times the size of an object on a screen located 4.20 m from the object. a) Is the mirror required concave or convex? concave convex     (b) What is the required radius of curvature of the mirror?  m (c) Where should the mirror be positioned relative to the object?  m from the object

Most side mirrors on cars have the warning "Objects in mirror are closer than they appear." This is because the mirror is not a plane mirror (it is not completely flat). It is a convex mirror. You reason that your particular mirror has a focal length of f = -12 m. The image of a cyclist in the mirror appears to be a distance of 3.1 m away from the mirror. (a) Do convex mirrors form real images or virtual images? virtual ✓ (b) How far away from the mirror is the cyclist? (find the object distance). Think about the sign of the image distance (is it real or virtual?). m (c) What is the magnification of the cyclist? Pay attention to the sign of your answer (+). (d) Is the image upright or inverted?

A spherical mirror is to be used to form an image 4.00 times the size of an object on a screen located 6.00 m from the object. (a) Is the mirror required concave or convex? O concave convex (b) What is the required radius of curvature of the mirror? (c) Where should the mirror be positioned relative to the object? m from the object
