Principle of image formation on the retina of an eye
Summary
[edit]
| Description |
Français : Principe de formation de l’image d’un objet sur la rétine (qui sert d’écran) dans un œil normal, suivant le principe de la lentille optique : une image nette se forme au fond de l’œil, au moins au centre de la rétine. La pupille qui fait office de diaphragme et qui régule la quantité de lumière pénétrant dans l’œil n’est pas représentée. L’image de l’objet est inversée : le bas devient le haut, la droite devient la gauche et inversement. La lumière du soleil est blanche dans la réalité, elle est formée des couleurs de l’arc en ciel et seule la couleur qui n’est pas absorbée par l’objet est renvoyée vers l’œil et apparaît comme étant la couleur de l’objet.
English: Principle of formation of the image of an object on the retina (which serves as a screen) in a normal eye, according to the principle of the optical lens: a sharp image is formed at the back of the eye, at least in the center of the retina. The pupil, which acts as a diaphragm and regulates the amount of light entering the eye, is not shown.The image of the object is reversed: bottom becomes top, right becomes left and vice versa. Sunlight is white in reality, it is formed from the colors of the rainbow, and only the color that is not absorbed by the object is reflected back to the eye and appears to be the color of the object. |
