our eyes
Wednesday, July 29, 2009
okay, im suppose to be reading Physiology : Special Senses, THE EYE.
but here i am, scribbling this down..
Okay, baru just now i read about "color vision". HUH! baru nak baca! =.="
then, the book said, our cone cells ,(a receptor dlm biji mata kte) are responsible for our color vision.
what is color? color is nothing but lights of different wavelengths in the spectrum. (This is how far my understanding goes.. haha.. )
So, if korang da blaja simple science mase zaman tadika dulu,
selain the "ROY G BIV" or "Micheal Jackson Kene ......." (Our rainbow colors), there are other lights in the spectrum kn?
cth : infrared, ultraviolet, microwave , or nak simpleeeee kn lah "bluetooth" korang tu...
kenape kte tak nmpk bende2 tu?
well, bcoz those wavelength is out of our visible range.
satu lagi sbb is bcoz those lights(rays) is not absord by our photoreceptor. FHM?
okay, fine, next, if we see roses are red, violets are blue..
is it bcoz roses emit RED lights, or violets emit BLUE light????
TIDAK SAMA SEKALI...
kan dah belajar dulu, kalau nampak kaler hijau, maksud nya bende tu reflect kan kaler yg hijau dan absorb kn kaler yg lain.
so , roses absorbs all the visible light of different wavelengths, and reflect only a group of visible we preceived as red, or pendek kata, REFLECT RED wavelength.
FAHAM?
so, black color absorbs all or white color absorb all?? Jawab jgn tak jawab.
p/s : BLIND EYE DOESNT SEE BLACK, IT SEES NOTHING.. duh~
NEXT, complementary color = when mixed in the proper proportion, they produce a neutral color (grey, white, or black). <- menurut wikipedia. so, if we nampak white paper, actually what is the color of the paper?? is it blue, green , or red? bcoz...... THE BOOK SAID : when 2 colors are mixed in appropriate amounts, it will lead to cancellation of other color sensations producing only sensation of "WHITE" (page 1156, ak jain) i knowwww, i dun get it too. =.=" or am i not digesting it properly?
