The telescope is an important astronomical tool that gathers and focuses electromagnetic radiation. Telescopes serve to both increase the angular size and the brightness of objects. When we speak about telescopes we are usually referring to optical telescopes‚ but many other types of telescopes also exist for other spectrum of electromagnetic radiation. It is unclear as to who it was that actually invented the telescope but Galileo Galilei is credited as being the first to use a telescope for

What are some advantages and disadvantages of a light microscope and electron microscope? Some of the disadvantages of the light microscope include‚ that since it send light‚ the light waves are diffracted as they pass through the matter. Because of this‚ light microscopes can only produce clear images of objects to a magnification of about 1000 times. Another problem is that since most living cells are nearly transparent‚ you can’t see them. So you have to use dyes to stain them. The advantage

Controlled assessment research Focus length of a lens- The most important characteristic of a lens is its principal focal length‚ or its inverse which is called the lens strength or lens "power". Optometrists usually prescribe corrective lenses in terms of the lens power in diopters. The lens power is the inverse of the focal length in meters: the physical unit for lens power is 1/meter which is called diopter Convex- The word convex means curving out or bulging outward‚ as opposed to concave

Investigatory Projects in Physics | Repulsorlifts as a Method of Stable Magnetic Levitation | Repulsorlifts were used in the study to find out if they can be used to replace the wheels of a conventional car. It was hypothesized that it will be able to lift a car using magnetic repulsion forces. The different magnets were tested individually with the usual tests for magnetic strength‚ size‚ and temperature increase‚ which were done in the preliminary testing. The prototype road and car were

(NATALIE) For the bubbleheaded young Narcissus of myth‚ the mirror spun a fatal fantasy‚ and the beautiful boy chose to die by the side of a reflecting pond rather than leave his “beloved” behind. For the aging narcissist of Shakespeare’s 62nd sonnet‚ the mirror delivered a much-needed whack to his vanity‚ the sight of a face “beated and chopp’d with tann’d antiquity” underscoring the limits of self-love. Whether made of highly polished metal or of glass with a coating of metal on the back‚ mirrors
