Introduction to optics and wave properties

This presentation is a detailed but easy to understand on the topic of optics. Any one who is looking to delve deeper into the optics topic in physics this would be a great introduction to the subject. So for anyone trying to get the Fundamentals on optics this topic will cover lenses and mirrors. Converging and diverging and all there is to know for a bigginer.

3. What is light

4. The classical description of light

7. •By The EM spectrum

14. Images
•Virtual–Seen in the mirror and exist
in the brain.
•Real–form on screens and other
surfaces.

i = Image distance (Taken negative)
Plane Mirrors

o+ 1/d
i = 1/f
Spherical mirrors

18. 1 -A ray that is initially parallel to the central axis reflects through the focal point F.
2 -A ray that reflects from mirror after passing through F emerges parallel to the central axis.
3 -A ray reflecting from mirror after passing through C returns along itself.
4 -A ray reflecting from point C is reflected symmetrically about that axis.
