Objectives

To study this unit it is advisable to have already studied WAVES.

In Optics you will learn:

-  To distinguish when light behaves as a particle and when it behaves as a wave.

-  What reflection is and how a ray of light behaves when it hits a flat, concave or convex mirror.

-  To understand what refraction is and how light behaves when it passes through convergent and divergent lenses.


-  To understand the way a telescope works and to know what to look for if you go to buy one.

-  The way a photoelectric cell works and what consequences you can deduce from it.
