  1. Reflections in Curved Mirrors 7SCIENCE

  2. Curved mirrors • Not all mirrors are flat, some may be circular in shape and curved • Curved mirrors exist for different purposes • Concave • Convex • Light rays travel in parallel (straight) lines and strike the mirror and are reflected

  3. Concave mirrors • Light rays reflect and meet at one point • Reflected through a point called the focal point • The distance between the focal point to the center of the mirror is called a focal length

  4. Concave mirror • Concave = forms a ‘cave’ like inside of a spoon • The image formed depends on the distance of the object from the focal point of the mirror • If the object is between the focal point and the mirror, the image appears inverted (upside down) and smaller • If the object is past the focal point, the image appears upright and larger

  5. Convex mirror • Curves outward ex. outside of a spoon • Causes light rays to spread apart • Image is always upright and smaller than the object • Ex. Security mirrors, car/truck mirrors • “things are larger and closer than they seem”
