WHAT IS METAL? A metal is a chemical element that is a good conductor of both electricity and heat. Metals are malleable and ductile and have lustrous appearance. They have moderate to high physical constants and high tensile strength. Metals are further divided into two main groups - ferrous and non ferrous metals. TYPES OF METAL • FERROUS METAL These are metals which contain iron. They may have small amounts of other metals or other elements added‚ to give the required properties

The Laser Before we can learn about the laser we need to know a little bit about light (since that is what a laser is made of). Light from our sun‚ or from an electric bulb‚ is called white light. It is really a mixture of all the different colours of light. The colours range from violet‚ indigo‚ and blue‚ to green‚ yellow‚ orange‚ and red. These make up the visible part of the electromagnetic spectrum. Light is made up of particles‚ called PHOTONS‚ which travel in waves. The difference in

A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The term "laser" originated as an acronym for Light Amplification by Stimulated Emission of Radiation.[1][2] Lasers differ from other sources of light because they emit light coherently. Its spatial coherence allows a laser to be focused to a tight spot‚ and this enables applications like laser cutting and laser lithography. Its spatial coherence also keeps
