Introduction to Thermodynamics

Science > Physics > Themodynamics > Introduction In this article, we shall study the concept of thermodynamics and thermodynamic state. Thermodynamics is a branch of physics that deals with the inter-conversion between heat energy and any other form of energy. Thermodynamic State: The simplest example of a system to which thermodynamics can be applied is […]

Simple Machines: Levers

Science > Physics > Simple Machines > Levers A simple machine is a mechanical device that makes our life easier. If a force is applied at one point, the simple machine transmits it to another point with a convenient change of magnitude and direction. In this article we shall study the terminology associated with the […]

Refraction Through Prism

Science > Physics > Refraction of Light > Refraction Through Prism In this article, we shall study refraction through prism. Prism: A prism is a portion of a transparent medium which is bounded by non-parallel plane surfaces. The two plane surfaces ABCD and AEFD intersecting each other in line AD are called the refracting faces […]

Natural Radioactivity

Science > Physics > Nuclear Physics > Natural Radioactivity Radioactivity was discovered by French physicist Antoine Becquerel in 1896. He found that certain compounds of uranium emitted invisible radiations which affected photographic plates. It is also found that Thorium and its compounds also show these properties. Madame Curie and Piere Curie discovered two elements namely […]

Introduction to Reflection of Light

Science > Physics > Optics > Reflection of Light > Introduction to Reflection of Light When a ray of light approaches a smooth polished surface and the light ray bounces back, it is called the reflection of light. The surface which reflects the light is called a reflecting surface. The ray of light approaching the […]
