Optics Mirrors and Lenses Reflection We describe the path of light as straight-line rays Reflection off a flat surface follows a simple rule: angle in (incidence) equals angle out (reflection) angles measured from surface “normal” (perpendicular) Reflection Vocabulary Real Image – Image is made from “real” light rays that converge at a real focal point so the image is REAL Can be projected onto a screen because light actually passes through the point where the image appears Always inverted

For other uses, see Lens. A lens. Lenses can be used to focus light. A lens is an optical device which transmits and refracts light, converging or diverging the beam.[citation needed] A simple lens consists of a single optical element. A compound lens is an array of simple lenses (elements) with a common axis; the use of multiple elements allows more optical aberrations to be corrected than is possible with a single element. Lenses are typically made of glass or transparent plastic. Elements

Studying the Stars: How the Telescope Changed Astronomy As long as humans have been able to see, they have looked at the stars with either with worship or with wonder. The earliest cultures of humanity created their deities from the heavens, most of which were seating upon the glowing specks of light that show through the black night sky. Humans only have a few senses that let them interact with and receive information from the environment, sight being the most useful. Trying to figure out what

falling under this category which has uses in day to day life of the common people as well as corporate employees. Every part of the body has got its body adaptive device which enhances the working of the body part. For example telescopic contact lenses which are worn on eyes have power to zoom. Also there are devices designed to amplify the sound of hearing. The advantages of using these devices include low cost devices as they are more commonly used, privacy is managed so that data can be gathered

Phase Contrast Microscopy Phase Contrast Microscopy, first described in 1934 by Dutch physicist Frits Zernike, is a contrast-enhancing optical technique that can be utilized to produce high-contrast images of transparent specimens, such as living cells (usually in culture), microorganisms, thin tissue slices, lithographic patterns, fibers, latex dispersions, glass fragments, and subcellular particles (including nuclei and other organelles). In effect, the phase contrast technique employs an optical
