Newton’s law of universal Gravitation states that a particle attracts every other particle in the universe using a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers. Gravitation Gravitation is the force by which every mass or particle of matter, including … Read more
Motion Motion is a change in position of an object with respect to time. Motion is typically described in terms of displacement, distance, velocity, acceleration, time and speed. The branch of physics which deals with the study of motion of material objects is called mechanics. Mechanics is divided into following branches. (i) Statics : Statics … Read more
Holography Holography, means of creating a unique photographic image without the use of a lens. The photographic recording of the image is called a hologram, which appears to be an unrecognizable pattern of stripes and whorls but which—when illuminated by coherent Light, as by a laser beam—organizes the light into a three-dimensional representation of … Read more
Radio activity Radioactivity is a physical process. As the name implies it is the act of emitting radiation spontaneously. In simple terms if atomic nucleus is unstable and want to loose some energy, it will release energy in the form of radiations. There are several types of particles or waves that may shoot out of … Read more

Electro Magnetic Induction When a DC current passes through a long straight conductor a magnetising force, H and a static Magnetic Field, B is developed around it If the wire is then wound into a coil, the magnetic field is greatly intensified producing a static magnetic field around itself forming the shape of a bar … Read more
Relation between focal length and redius of curvature The focal length (f) of a lens is the distance between the center of the lens and the point at which the reflected Light, of a beam of light travelling parallel to the center line, meets the center line (principal axis). The radius of curvature (r) is … Read more
