WebThe cornea and lens can be treated as a single thin lens, even though the light rays pass through several layers of material (such as cornea, aqueous humour, several layers in the lens, and vitreous humour), changing direction at each interface. The image formed is much like the one produced by a single convex lens. This is a case 1 image. WebA virtual image is formed when light rays appear to diverge from a point without actually doing so. Figure 16.5 helps illustrate how a flat mirror forms an image. Two rays are shown emerging from the same point, striking the mirror, and reflecting into the observer’s eye.

Some of this light enters the eye through an opening called the pupil (PYOO-pul). The iris (the colored part of the eye) controls how much light the pupil lets in. Next, light passes through the lens ... WebIf the object is an extended object and not a point object then the image formed on the retina is NOT a point image. All the light rays coming from one point on the image are focused on one point on the focal plane i.e. the retina.

WebLight rays change direction when they reflect off a surface, move from one transparent medium into another, or travel through a medium whose composition is continuously changing. The law of reflection states that, on reflection from a smooth surface, the angle of the reflected ray is equal to the angle of the incident ray. (By convention, all angles in … WebThe objective collects a fan of rays from each object point and images the ray bundle at the front focal plane of the eyepiece.
