\u0388πρεπε ο \u03acνθρωπος να ανακαλ\u03cdψει τον ηλεκτρι- σμ\u03cc, τα φ\u03ceτα, να εντοπ\u03afσει και απομον\u03ceσει μονοχρωματικ\u03ac τις φωτειν\u03adς ακτινοβολ\u03afες για να εννο\u03aeσει καλ\u03cdτερα, πειραματισθε\u03af και ασχοληθε\u03af με την προσθετικ\u03ae μ\u03afξη των χρωμ\u03acτων.<\/span><\/span><\/p>\n

Αναπολ\u03ceντας λοιπ\u03ccν την ιστορ\u03afα του ανθρ\u03ceπου και τα τεχνολογικ\u03ac του επιτε\u03cdγματα, καταλα- βα\u03afνουμε π\u03ccσο πρ\u03ccσφατη ε\u03afναι η σχ\u03adση του με τη μ\u03adθοδο αυτ\u03ae, τη γνωστ\u03ae σαν <\/span>R<\/span><\/strong> <\/span>(<\/span>red<\/span> = κ\u03ccκκινο<\/span>) <\/span>G<\/span><\/strong> <\/span>(<\/span>green<\/span> = πρ\u03acσινο<\/span>) <\/span>B<\/span><\/strong> <\/span>(<\/span>blue<\/span> = μπλε<\/span>). Η εφαρμογ\u03ae αυτο\u03cd του συστ\u03aeματος μπ\u03aeκε στη ζω\u03ae μας με την αν\u03acπτυξη της \u03adγχρωμης τηλε\u03ccρασης, εκε\u03af γ\u03cdρω στα μ\u03adσα του εικοστο\u03cd αι\u03ceνα, εν\u03ce απ\u03cc τη δεκαετ\u03afα του 1980 και \u03cdστερα, με τη ραγδα\u03afα εξ\u03adλιξη των ηλεκτρονικ\u03ceν υπολογιστ\u03ceν, ενσωματ\u03ceθηκε στην καθημεριν\u03ccτητ\u03ac μας.<\/span><\/span><\/p>\n

Τα βασικ\u03ac χρ\u03ceματα των μονοχρωματικ\u03ceν ακτινοβολι\u03ceν ε\u03afναι το μπλε<\/span>, το πρ\u03acσινο<\/span> και το κ\u03ccκκινο<\/span>. \u038cταν η μια ακτινοβολ\u03afα προσπ\u03afπτει επ\u03af της \u03acλλης, προστ\u03afθενται οι ιδι\u03ccτητες και των δυο και παρ\u03acγεται μια τρ\u03afτη. Κ\u03acθε ζε\u03cdγος βασικ\u03ceν ακτινοβολι\u03ceν μας αποδ\u03afδει μια \u03acλλη και συνολικ\u03ac \u03adχουμε τρεις παρ\u03acγωγες μονοχρωματικ\u03adς ακτινοβολ\u03afες.<\/span><\/span><\/p>\n

\u0388τσι λοιπ\u03ccν \u03adχουμε:<\/span><\/span><\/p>\n

 <\/p>\n

Μπλε<\/span> + πρ\u03acσινο<\/span> = κυαν\u03cc<\/span><\/span><\/span><\/p>\n

Μπλε<\/span> + κ\u03ccκκινο<\/span> = ματζ\u03adντα<\/span><\/span><\/span><\/p>\n

Κ\u03ccκκινο<\/span> + πρ\u03acσινο<\/span> = κ\u03afτρινο<\/span><\/span><\/span><\/p>\n

 <\/p>\n

 <\/p>\n

\u038cπου συμπ\u03adσουν και οι τρεις βασικ\u03adς ακτινοβολ\u03afες παρ\u03acγεται λευκ\u03cc φως. <\/span><\/span><\/p>\n

\u038cπου δεν υπ\u03acρχει καθ\u03ccλου φως \u03adχουμε μα\u03cdρο σκοτ\u03acδι.<\/span><\/span><\/p>\n

Additive color mixing<\/span><\/span><\/span><\/p>\n

 <\/p>\n

Additive mixing of colors refers to the color mixing of monochromatic radiations and although thereto based the whole natural color rendering, for man is something relatively new.<\/span><\/span><\/span><\/p>\n

Man had to discover electricity and electrical lights, to identify and isolate the monochromatic light radiation to understand better, experiment and deal with the additive mixing of colors<\/span><\/span><\/span><\/p>\n

So, retracing the history of human and his technological achievements, we see moving how recent is his relationship with this method, known as R (red) G (green) B (blue). The adjustment to this system came into our life with the development of color television, there around the middle of twentieth century and from the 1980s onwards, with the rapid development of computers, integrated in our daily living.<\/span><\/span><\/span><\/p>\n

The primary colors of monochromatic radiation are blue, green and red. <\/span><\/span><\/span><\/p>\n

 <\/p>\n

When a radiation is incident on another, their properties are added and the produce a third one. Every basic radiation pairs to another and in total there are three derivative monochromatic radiations.<\/span><\/span><\/span><\/p>\n

 <\/p>\n

So we have:<\/span><\/span><\/span><\/p>\n

 <\/p>\n

Blue + green = cyan<\/span><\/span><\/span><\/p>\n

 <\/p>\n

Blue + red = magenta<\/span><\/span><\/span><\/p>\n

 <\/p>\n

Red + green = yellow<\/span><\/span><\/span><\/p>\n

 <\/p>\n

Where coincide all the three main radiations produced white light.<\/span><\/span><\/span><\/p>\n

 <\/p>\n

Where there is no light (radiation) at all we have black darkness.<\/span><\/span><\/span><\/p>\n
