  ## Reflection and refraction of light
  
  • LIGHT is another common type of energy.
  • You parents or educators would like to have "eyes at the back of their heads" or would like you to believe that they see everything. We know that this is impossible, though, and for a simple reason.
  
  ## Light travels along a straight line.
  
  Light can change direction, though, and this happens in two ways:
  
  • Refraction
  • Reflection
  
  REFLECTION: We are going to look at reflection as it occurs with mirrors.
  
  When a beam of light arrives at a certain angle, it will be reflected at the same angle.
  
  ANGLE OF INCIDENCE = ANGLE OF REFLECTION
  
  ## To establish concepts relating to reflection [lo 2.4]
  
  Assignment 1:
  
  1. Draw a sketch of a mirror, showing the angle of incidence and the angle of reflection. Use a protractor.
  
  Assessment of the Sketch
  
  Has the sketch been drawn correctly?
  
  [LO 2.4]
  
  Curved mirrors
  
  Curved mirrors have many applications. They enlarge or diminish and distort the image. A curved mirror can be CONCAVE. This will CONVERGE light beams towards a fixed point, the FOCUS.
  
  Other mirrors may be CONVEX . They will cause light beams to DIVERGE (spread apart). This scales down the image. An application of this is evident in the rear view mirror of a motor car or in wing mirrors.
  
  The same effect can be achieved with polished metals.
  
  Assignment 2:
  
  1. Try the following:
  
  Polish the surface of a large serving spoon to get it to shine.
  
  Look at your own image in the concave and on the convex side of the spoon and compare the shape of the reflections.
  
  Draw the differences in the spaces that are provided:
  
   Concave Convex
  
  Assessment of Sketches
  
  Were you able to complete the sketches correctly?
  
  [LO 2.4]
  
  ## Assessment
  
  LO 2: Constructing Science Knowledge:
  
  The learner will know and be able to interpret and apply scientific, technological and environmental knowledge.
  
  This is evident when the learner:
  
  • recalls meaningful information;
  • interprets information;
  
  2.4 applies knowledge.

  where we get a research paper on Nano chemistry....?
  nanopartical of organic/inorganic / physical chemistry , pdf / thesis / review
  Ali
  what are the products of Nano chemistry?
  There are lots of products of nano chemistry... Like nano coatings.....carbon fiber.. And lots of others..
  learn
  Even nanotechnology is pretty much all about chemistry... Its the chemistry on quantum or atomic level
  learn

  no nanotechnology is also a part of physics and maths it requires angle formulas and some pressure regarding concepts

  I only see partial conversation and what's the question here!
  what about nanotechnology for water purification
  please someone correct me if I'm wrong but I think one can use nanoparticles, specially silver nanoparticles for water treatment.
  Damian
  yes that's correct
  Professor
  I think

  Nasa has use it in the 60's, copper as water purification in the moon travel.

  what is the stm
  is there industrial application of fullrenes. What is the method to prepare fullrene on large scale.?
  Rafiq
  industrial application...? mmm I think on the medical side as drug carrier, but you should go deeper on your research, I may be wrong

  if virus is killing to make ARTIFICIAL DNA OF GRAPHENE FOR KILLED THE VIRUS .THIS IS OUR ASSUMPTION
  Anam
  analytical skills graphene is prepared to kill any type viruses .

  Any one who tell me about Preparation and application of Nanomaterial for drug Delivery
  Hafiz
  what is Nano technology ?
  write examples of Nano molecule?
  Bob
  The nanotechnology is as new science, to scale nanometric
