Basic purpose of this lecture is to present on What is an Optical System. In optics, an image-forming optical system is a system capable of being used…

This lecture introduce on difference between Reflection and Refraction. When a wave reaches a boundary it is: Partially reflected (bounces off surface) and Partially transmitted through surface. Reflection…

There are 2 basic types of lenses: Convex and concave lens. A converging lens (Convex) takes light rays and bring them to a point. A diverging lens (concave) takes light…

Principle purpose of this lecture is to present on Curved Mirrors. It is a tutorial study based lecture. A convex mirror is a spherical reflecting surface (or…

Spherical mirrors are mirrors whose surfaces form a part of a hollow sphere. The spheres can be made of glass or any polished metal surfaces.…

Dissipative System is a term of physics, which is a thermodynamically open system. It is operating out of, and often far from, thermodynamic equilibrium in…

Major purpose of this lecture is to present on Optics and Mirrors. Rays seem to come from behindthe mirror, but, of course, theydon’t.  It is virtually as…

The aim of this lecture is to present on Reflection. Law of Reflection: the angle of incidence equals the angle of reflection. The angle which the incident ray…

Adaptive System is a system that changes to improve its performance or chances of survival by monitoring and adjusting its own configuration and operations in…

Prime purpose of this lecture is to present on Light: Geometric Optics. Light travels in straight lines under a wide variety of circumstances. Light travels in straight line…

Literate Programming can be regarded as an essayist, whose main concern is with exposition and excellence of style. Literate programming paradigm, the central activity of…

General purpose of this lecture is to present on Light and Optics. Optics is the branch of physics which involves the behaviour and properties of light, including…
