  • define refraction
    obliquely, bending, two medium
  • use of convex lens
    microscopes, specs
  • rules of refraction
    r d t d r a
  • in convex lens, object between 2f and f, image will be at
    beyond 2f
  • define despersion
    splitting of white light
  • in convex lens when object is at infinity....image will be at
    focus, point size, real
  • how is speed of light and optical density related?
    inversely proportional
  • in convex lens when object is at 2f, image will be at
    2f, same size, real, inverted
  • why do we get violet near the base in despersion
    maximum bending, least speed
  • in convex lens when object is between f and o, image will be
    in same side, virtual, erect, magnified
  • formula of relative refractive index
    speed of light in med1/ speed of light in med 2
