Announcements Reflection <strong>and</strong> Refraction <strong>Image</strong> <strong>Formation</strong> Final QuestionsConvex mirrorsWe can also form an image using a convex mirror, that is, one that reflects light from its outer, convexsurfaceIt is sometimes referred to as a diverging mirror, because rays from any point on an object diverge afterreflectionWe will not derive any equations for convex spherical mirrors because our earlier equations can be used forboth concave <strong>and</strong> convex mirrorsSign conventions for mirrorsQuantity Positive When ...
