WebMar 16, 2024 · Rule 2 - Ray passing through focus will become parallel to principal axis after reflection. For a concave mirror , we see that ray passing through focus becomes parallel to principal axis after reflection. For a convex mirror, since focus is on the right side, it appears that ray passes through focus, and then it becomes parallel to principal axis. WebThe first ray runs parallel to the principal axis between object and lens (called the parallel ray). It is refracted at the lens and crosses the optic axis at the back focal point (F′) behind the lens. The second ray travels from the object extremity through the intersection of the lens centre and the optical axis (the principal ray). how can we generate oxygen on mars

WebJul 1, 2024 · I was trying to prove that during reflection from a concave mirror, all rays parallel to the principal axis will meet the principal axis at a point (focus) that is equidistant from the centre of curvature and the pole. I thought of proving this using coordinate geometry (and some trigonometry). WebA concave lens refracts parallel rays in such a way that they are bent away from the axis of the lens. For this reason, a concave lens is referred to as a diverging lens. A) Consider the following diagrams, where F represents the focal point of a concave lens.
