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 … Read more
Elementary idea of LASER Laser, a device that stimulates atoms or Molecules to emit Light at particular wavelengths and amplifies that light, typically producing a very narrow beam of radiation. The emission generally covers an extremely limited range of visible, infrared, or ultraviolet wavelengths. Many different types of lasers have been developed, with … Read more
Climate Change It is the long term change in the statistical distribution of weather patterns over periods of time Though it has been happening naturally for millions of years, in recent years it has accelerated due to anthropogenic causes and has been causing Global Warming. UNFCCC defines Climate Change as – “a change of climate … Read more
Medium of Propagation Sound is a sequence of waves of pressure which propagates through compressible media such as air or water. During their propagation, waves can be reflected, refracted, or attentuated by the medium. The purpose of this experiment is to examine what effect the characteristics of the medium have on sound. Ground Wave or … Read more
Factors affecting Photosynthesis Light Without light, a plant cannot photosynthesize very quickly, regardless of whether there are water and CO2 or not. But overdoing light is also not a good idea. In nature, balance is crucial. But increasing the intensity of light to a prudent limit will speed up the process. Carbon Dioxide … Read more
The Rate of a Chemical Reaction The rate of a chemical reaction can be defined as the amount of the reaction which occurs in unit time. The rate of a reaction is measured by choosing certain properties of the reaction which will indicate how far the reaction has gone, and whose magnitude can be observed … Read more

Electrostatic The basic principle of Electrostatics is based on the fact the electric charges attract or repel other charges depending on their relative signs and the law of force is given by Coulomb‘s law. Coulomb’s law states that: The magnitude of the electrostatic force of interaction between two point charges is directly proportional to the … Read more
