Process (How to do the activity)

Take a Convex Lense and place it before a thick book which has a dark background.Keep a Comb in front the Lense.Now pass the light using the torch through the lense.Observe the path of the light rays. They converge at a point.

Now replace the convex lense with the concave lense and continue the procedure and obseve the path of the light rays. They appear as diverging from a point

Developmental Questions (What discussion questions)

  1. Name the types of Lenses
  2. What happens when light rays pass through the glass ?

Evaluation (Questions for assessment of the child)

  1. Which lense converges the light rays?
  2. Which lense diverges the light rays?

Question Corner
