MIRRORS and THEIR TYPES

Mirror can reflect the light due to its non transparency property...the surface where light reflects is called reflecting surface. CLASSIFICATION OF MIRRORS 1. Plane mirrors 2. Spherical mirrors principles of reflection: 1. The angle of incidence is equal to the angle of reflection 2. Incident ray, reflected ray and Normal lie in the same plane. They are coplanar.&nbs...

types of objects and images

NATURE OF OBJECTS AND IMAGES Ray optics primarily deals with determining the position and nature of the image formed when an object is placed in front of an optical element. TYPES OF OBJECTS: An object is a source of light rays that are incident on an optical element.  An object may be a point or an extended object.  Since extended objects can be modeled as a collection of points, we only need to study point objects. REAL OBJECT: An object is real if two or more incident rays actually emanate or seen to emanate from a point.  The...

GEOMETRICAL OPTICS - BASIC CONCEPTS

INTRODUCTION: What is light? Light is the energy emitted by the excited atoms which can cause the sensation of vision in a human eye, hence light is a form of radiant energy. What is optics? The branch of physics which deals with the phenomena concerning light is called optics . We can classify the optics into : 1) Geometrical optics 2) Physical optics. What is Geometrical optics? The study involves, the light is considered as moving along a straight line as moving along straight line as a ray. A ray of light gives the direction of light....
