1. experence on light through....

   • convex lenses
     • converge light

     • curved piece pf glass, thicker in the middle than at the edge
     • magnifying glass
     • camera
   • concave lenses
     • diverge light
     • divergent rays
     • curved piece pf glass, thinner in the middle than at the edge
     • flash lights
     • peephole

2. light bends through different media

   • refraction
     • hits critical angle
       • total internal reflection
         • diamonds
         • cat eyes
         • optical fibre
     • glass to air
       • lower speed to higher speed
       • bends away from normal
     • air to glass
       • bends towards normal
       • higher speed to lower speed
