Another important characteristic of a thin lens is that light rays through its center are deflected by a negligible amount, as seen in Figure 25.30. Refraction of light. The three rays cross at the same point on the other side of the lens. Science House. But the image is farther away, a fact that is useful in correcting farsightedness, as we shall see in a later section. di/dom= f Light enters a container of liquid at an angle of 37 to the normal; the refracted beam makes an angle of 27 with the normal. Ray Diagrams This page is about how we scientists draw diagrams to show how light travels, some bits are straight forward (mirror) but some get very complicated (total internal refraction). That is, light rays from one point on the object actually cross at the location of the image and can be projected onto a screen, a piece of film, or the retina of an eye, for example. Net Force (and Acceleration) Ranking Tasks, Trajectory - Horizontally Launched Projectiles, Which One Doesn't Belong? The distance at which the image blurs, and beyond which it inverts, is the focal length of the lens.
