Introduction A mirror formula is a way to predict the relationship between three critical points of the mirror – the distance of the object, the distance of the image and the mirror’s focal length. The distance of the object placed is represented by “u”, the distance of the image formed is denoted by “v” and […]

Mirror equation is an experimental-based quantitative interrelationship between object distance, image distance, and focal length. The fundamental principles of the new Cartesian sign convention are used to understand the positions of the object, image, and mirror better. Concepts related to mirror equations and formulas are applied to spherical mirrors only. This article will help in

Microscopy is the study of using a microscope to examine small objects and structures in greater detail. The term “microscopic” refers to something that is undetectable to the naked eye until examined under a microscope. There are many distinct types of microscopes, and they can be classified in a variety of ways. To describe the

Introduction Microscopes and telescopes are two powerful instruments that have greatly aided our current understanding of the micro-and macrocosm. The development of these gadgets resulted in major breakthroughs in fields like physics, astronomy and biology, to name a few.  Microscopes and telescopes both work by allowing individuals to see items that aren’t visible to the

Introduction A telescope is an optical tool used to make distant things appear closer. It is composed of a series of lenses or reflective surfaces and lenses by which light rays are accumulated and concentrated, and the image obtained is enlarged. Microscopes and telescopes  work similarly. They allow individuals to see objects which are not

Introduction Within a limited range of the electromagnetic spectrum, the retina (inner eye) of the human has been programmed by nature to detect electromagnetic waves. A wavelength ranging from 400 nanometers to 750 nanometers is considered to be visible light of electromagnetic radiation. We learn and interpret the world around us primarily through light and

Magnification is the process of enlarging something’s apparent size rather than its actual size. The amount of enlargement is expressed as a numerical value called “magnification.” When this number is less than one, it indicates a size reduction, also known as minification or de-magnification. Furthermore, this notion has two variations. The first is through a

If you talk to a group of cell biologists about what they enjoy most about their jobs, you could discover that it all boils down to one thing: they’re all secretly microscope geeks. What they truly enjoy is sitting in a small, dark room for hours on end, communing with their preferred cell type through

A lens is a piece of transparent material that is generally round in form and has two polished surfaces, one or both of which is curved and may be convex (bulging) or concave (not bulging) (depressed). Curves are usually always spherical, which means that the radius of curvature is constant. The ability of a lens

Introduction In General ray drawings can be used to determine the location of the image, the size, shape and type of the image built of objects when placed somewhere in front of the lens. Ray drawings provide useful information about image-object relationships, yet fail to provide information in the quantitative form. While a ray diagram
