law of reflection
Law of Reflection
  • Angle of incidence equals the angle of reflection
  • Whatever angle the light hits the surface, it will bounce back at the same angle
however
However…..

….the shape of the reflecting surface affects the way light reflects from it

plane mirror
Plane Mirror
  • Has a flat surface
  • Reflection is upright and same size
  • Images are reversed
  • Examples: bathroom mirror, rearview mirror in a car
concave mirror
Concave Mirror
  • Curved inward
  • If the object is close to the mirror, the image is enlarged and upright
  • If the object is far away, the image is reduced in size and upside down
  • Examples: inside of a spoon, reflecting telescope, inside of a flashlight
convex mirror
Convex Mirror
  • Curves outward
  • The image is upright and smaller
  • Useful because they allow you to see a large area
  • Examples: side mirrors on cars, back of a spoon, used for security
convex lens
Convex Lens
  • Thicker in the middle than at the edges
  • Light refracts towards the center (converges)
  • Examples: magnifying glasses, human eye, cameras, projectors
concave lens
Concave Lens
  • Thinner in the middle than at the edges
  • Light spreads out (diverges)
  • Examples: used in telescopes
nearsightedness myopia
Nearsightedness (Myopia)
  • Can only see an object clearly if its nearby
  • Eye is too long and the lens focuses light in front of the retina
  • Concave lens is used to correct this
farsightedness hyperopia
Farsightedness (Hyperopia)
  • Can only see an object clearly if its far away
  • Eye is too short and lens focuses behind the retina
  • A convex lens is used to correct this
