THE FOCAL LENGTH OF SPHERICAL MIRRORS Section 1: The Focal length of a concave mirror Section 2: The focal length of a convex mirror Done by: I.D: 201100635 24 Oct. 11 Section 1: To determine the focal length of a Concave Mirror by locating the centre of curvature. ------------------------------------------------- ABSTRACT: In this paper we want to discuss the focal point of a concave mirror by locating the centre of curvature. The focal point is a point in space at which light incident towards

Content for mails about photography Email 1: You WON 'T BELIEVE your DLSR could do these... DSLR camera has many features some of which may sound intimidating at first. The camera combines a host of optics and digital imaging sensor and single lens reflex camera mechanisms to capture shots. DSLR camera remain the most popular type of interchangeable lens camera in use today. The DSLR camera market is dominated by companies such as Canon, Nikon, Sony and Olympus from Japan as well as manufactures

resonator include the mirror surface quality, along with vibrational and thermal stability of the resonator. 33. F-number: unit used to measure the image brightness projected on the image sensor from the lens. The F-number of a lens is ratio of its focal length divided by the diameter of the aperture. High F-numbers show that less light travels through the lens. An f-number of X may also be displayed as 1: X (instead of f/X). The maximum diameter of the lens opening is referred to as its maximum aperture

PHYSICS 30123: Observational Astronomy – Fall 2015 LABORATORY 1: Jordan Adams Collaborator: Corey Nix PURPOSE: The aim of the investigation was to further our understanding of the physical laws that govern our ability to receive and interpret information in the form of visible light. We have all had a physics class that at least brushed the introduction of optics, but we can still further our comprehension by experimenting with optics that have different characteristics. Does one axis truly

50, 60, 70, 80-degrees. 8. Record all data into a table. Focal length of convex lens 1. Set up a screen across from window. 2. Place convex lens into mirror holder. 3. Place mirror holder at base of screen and slowly move away from the screen. 4. When image comes into focus, move slowly until image appears to be crisp. 5. Measure distance from screen to lens. 6. This is experimental focal point, record in data table. Testing focal length 1. Setup yard stick with screen at one end and candle at other

This essay reviews the painting by William Bouguereau’s The Elder Sister. It reviews the elements of design and principles practiced in the artwork. This essay assesses the correct use of the elements and the influence that they have on the entire perception of the painting. The artist has applied an amazing background as well as perfect balance of the piece. The elder sister's arm balances with her leg, the baby's foot balances with older sisters foot, the clouds balance with the bushes. This explains
