WHY OUR EYES SEE DIFFERENT COLORS?

Many people believe our eyes have a “camera” that can see to the outside world. That’s not true. We see colors because of wave and frequency. Every color we see is a product of light from the sun that enters our eyes. Then their specific wavelength number and frequency number are interpreted by the brain to tell us what color that combined wavelength and frequency is equivalent to. Example the color red, when a light enters the eyes and the brain received an information that the light has 420 THz frequency and a wavelength of 700 nm, then our brain will give us the picture of color red.

Our human eyes can only see within the range of 380-780 wavelength and 400-790 frequency. BELOW ( radio wave, infrared used in microwave) and ABOVE (UV, X-Ray, Gamma) the range of these waves and frequencies become invisible to our naked eye. Multiple waveleghts give us colors of pink, purple or magenta. In our visible spectrum, red has the lowest frequency but longest wavelength while violet has the highest frequency(668-790THz) and shortest wavelength(380-400nm). Whenever you see green, you’re seeing a light with frequency of 526-606 THz and a wavelength of 440-495nm. Animals like birds and bees can see below the human range as they can see within the infrared spectrum. Next time you want to think of color, think of its wavelength and frequency combined as the reason why you see it that way. You can memorize them for fun and for bragging.

The sun is the only source of all light and its light is an electromagnetic wave that travels through space at a speed of light of 300 MILLION METERS PER SECOND or 669.6 MILLION MILES PER HOUR. Every electromagnetic wave has its unique frequency and wavelength and like the color red for example it has a frequency of 428,570 BILLION CYCLES PER SECOND giving your eyes 400 TRILLION WAVES PER SECOND to receive. That’s why in the dark we cannot see any color because there is no wave and frequency that enters our brain to be interpreted into color but the minute we see even a little spark, our eyes will interpret that light because it has wave and frequency. Our body is a bunch of wave and requency and how we see, how we hear, how we feel all depends on the wave and frequency our brain received and interpreted.
