The present investigation develops that until the 16th century it was thought that light was infinite. Galileo to measure the speed of light and with the help of an assistant, both with a flashlight and about a mile apart, covered and uncovered the internal one, Galileo tried to measure time, his results failed, he said "the measurement was so great that it did not it could be measured ”. In 1676, Ole Roemer observed that one of Jupiter's satellites called Io did not have a constant rotation period. After gathering information for more than a year, he found that Io had a longer period than average when the Earth was moving away from Jupiter. It had a difference of 22 minutes than when the Earth was close to Jupiter from when it was away (6 months). He assumed that the light was slow to arrive, since there was too much distance, so it arrived with a delay of 22 min. Approximately 1320 seconds and in a calculation it got to obtain that the speed of the light was 214 000 km / s demonstrating that the speed of the light is finite. In 1849, Hypoite Fizeau used an ingenious experiment to make light from a strong light source strike a semi-plane mirror, which is deflected by passing it through the teeth of a gear. The speed of rotation of the gear can be changed at will. . Through this experiment, a speed value very close to the real number is obtained and the speed of light in water can also be measured. Later there were more successful tests with different experimenters and methods until the laser method was used where it gives us an exact value of the speed of light. The phenomenon of reflection is introduced into the concepts of angle of incidence and angle of reflection. The angle of incidence and the angle of reflection remain separated by an imaginary line called common that is perpendicular to the area of division of 104 both media. Incident light, reflected light, and usual light remain in the same plane, and the angle of incidence and the angle of reflection are equivalent. Fermat's onset of the shortest time points out that the royal path that a beam of light takes between 2 aspects is the shorter travel era. Once we talk about refractive index, it is mainly equal to the speed of light in vacuum. Total internal reflection, where n1 and n2 are the refractive indices of medium 1 and medium 2, respectively. As the angle of incidence increases, it is equal to 90 degrees and the refracted rays are parallel to the interface between the media. From that cost, reflection is everything. Therefore, in the reflection of a plane area, the image point is a suitable way of explaining the direction of various reflected rays. If the surface of the graphic is not smooth, it will diffuse when reflected and the light from different parts of the surface will follow irrelevant directions. In this case, there would be no defined image, we could not see our image. In spherical surfaces, the reflection can be concave or convex if the angle of incidence and the angle of reflection are equal. The norm to the surface is a radius. We can say that in mirrors when the object and the image are on the same side, then the image is real and if they are on opposite sides the image is virtual. On the other hand, in entities, if the object and the image are on the same side, then this is virtual, while if they are on opposite sides, it is real. Optical Tools are a mirror and lens application for imaging larger, smaller, closer, or more distant objects. Upa is a converging entity with a smaller seal distance, used to increase the size of the display object. 105 Observe the microscope with the eyepiece, the magnified image of the object given by the objective lens (converging lens), the objective lens is quite convergent and the object is out of focus but close to focus. A telescope called an astronomical telescope is a telescope because it can magnify images of celestial bodies. These are called refracting telescopes. It uses a converging lens system, in which light is refracted, and this refraction in the objective lens causes parallel light rays from a fairly distant object to converge at a certain point on the focal plane, or makes it possible to see the distance. object is old and shiny.
