Optics

1. Is when light travels to a surface with different densities, the same one is diverted to another direction with less intensity

2. Reflection of light

2.1. Is the change of direction of the light rays occurring in the same medium after impacting on the surface of a different medium.

3. Refraction of light and total internal reflection

4. What is optics?

4.1. It is the science belonging to physics that studies the laws, behavior, composition and expressions of light.

4.1.1. Geometric optics: studies the behavior of light propogated in straight lines.

4.1.1.1. Physical optics: consider light as waves, including all wave phenomena, such as diffraction, interference and refraction, among other

4.1.1.1.1. Quantum optics: linght is concidered a disturbanced a corpuscle, consisting of small particles that move and impact on objects, making them visibles.

5. Electromagnetic spectrum and visible spectrum

5.1. Electromagnetic spectrum: it is the type of range of all possible electromagnetic radiation.

5.1.1. Visible spectrum: is that band of colors that we can observe

6. Isaac Newton: The corpuscular theory of light could explain the phenomena related to related to reflection and refractio.

7. It tells about the story of how equations are formulated to know the "exact" speed of light and this is: 2.997925 X 10^8 m/s

8. Nature of light

8.1. It can be said that light has a dual nature, it es considered a wave. The sun is the most important source of light and natural energy.

9. Speed of light

10. In history there have been thinkers who have been charged with studying or putting ideas about natural light

10.1. Democritus: Believed that light was composed of a large number of particles.

10.2. Pythagoras: The light emanates from luminous bodies in all directions.

10.3. Aristotle: Light as kind of pulsation in this ether.

10.4. Epicurus of Samos: Light was emitted in the form of rays-

10.5. Leonardo da Vinci: First to relate light sound and waves.

10.6. Descartes: light was propagated in a dense universe and perceived through vibration.
