The complete verdict<\/strong><\/a> can be read on the website of the Master’s Degree in Physics and Technology of Lasers.<\/p>
Below we include the 4 award-winning photographs.<\/p>
1st Category: Light Technologies and Optical Phenomena.<\/strong><\/span><\/p>
First prize for the photograph entitled \u201cLevitation: the magic of planet Earth\u201d taken by D. Adri\u00e1n de la Fuente Ballesteros.<\/li><\/ul><\/li><\/ul>
Description: The image represents a hologram of planet Earth generated with a mobile phone and a piece of methacrylate in the shape of an inverted pyramid. It is a three-dimensional photograph that constitutes an optical duplicate of an object and allows it to be observed from different viewing angles.<\/p>
Second prize for the photograph entitled \u201cA celestial reflection\u201d taken by Ms. Mar\u00eda Flores Ceballos.<\/li><\/ul><\/li><\/ul>
Description: The image shows the well-known painting \u201cThe Sky of Salamanca\u201d and its reflection created with the help of a CD, which acts as a small flat mirror. In this way, the painting apparently forms a complete circle.<\/p>
2nd Category: The Laser.<\/strong><\/span><\/p>
First prize for the photograph entitled \u201cFl\u00faor Tonic\u201d taken by Ms. Blanca Dur\u00e1n Salvador.<\/li><\/ul><\/li><\/ul>
Description: Image where fluorescence is observed when we hit the tonic with a violet laser, comparing it with a green laser for which this phenomenon does not occur.<\/p>
Second prize for the photograph entitled \u201cConducting the Light\u201d taken by Mr. Mario Guerras Rodr\u00edguez.<\/li><\/ul><\/li><\/ul>
Description: We trap laser light in a flow of water that forms a parabola towards the ground. The total reflection effect appears and the light cannot leave the water until it reaches the ground, as if it were a fiber optic cable.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
