Lens applications My name is Darrin Mathewson and I have a PhD in organic chemistry. It describes how incident rays reflect off mirrors according to the law of reflection, forming reflected rays. It discusses that a telescope has two main components - an objective lens or mirror that gathers light, and an ocular lens or eyepiece that is used for ppt of light- physics chapter class 7 . Flat reflective surfaces or flat surfaces that allow that transmission of light . Real images are formed by converging light rays at a ppt of light- physics chapter class 7 . There are two main types of reflection: irregular/diffused reflection which scatters light in all directions for general illumination, and regular/specular reflection which forms images using smooth, shiny surfaces like mirrors. *Object*: The object being observed. Plane mirrors reflect light at an equal angle, forming a virtual upright image. Activity 1: Re ection O a Plane Mirror Equipment: light box, protractor, plane mirror.
