Light and Lenses

1. opaque:completely  blocking  light  from   passing  through.

2.  transparrent:letting  all  light  through, so  that  objects  on  the  other  side  can  be seen clearly.

3.translucent:letting  only  some  light  through, so  that  objects  on the other side  appear blurry.

4.polarization:allowing  light  vibrations  to  pass  through  in  only  one  direction.

5.refraction:the  bending  of  light  rays  as  they  pass  from  one  subtance into  another.
