GLENDA MARIE GARCIA POLARIZED LIGHT LAB REPORT EXPERIMENT # 5 June 27‚ 2014 PHYS 1417 ABSTRACT Ordinary light such as that from a light bulb is a form of wave motion that consists of electrical and magnetic fields that vibrate at right angles to the direction of travel of a light beam. Light waves that vibrate in a single plane are called polarized light waves. Such waves can be produced by passing light through polarizing filters. The experiment conducted was composed of crossed

Fusion Techniques for Multispectral and Panchromatic Images Abstract: Image fusion is the process of merging two or more images obtained from the same sensor at different times or from two or more sensors at the same instant. The objective is to obtain more information from the fused image than from the individual images. In satellite images‚ the lower spatial resolution multispectral images are fused with higher spatial resolution panchromatic images. The fusion should result in the transfer of

1. You are looking at a Euglena using the x10 objective lens. You rotate the nosepiece around to x40 but the specimen is not visible. Describe what you should do next? Start by using the fine adjustment to attempt to focus on the Euglena. However‚ if it is still not visible‚ return to the x10 objective lens and use the fine adjustment to ensure the Euglena is as sharply focused as possible. Then‚ use the stage control to re-position the slide so the Euglena is directly in the centre of the lens.

MICROSCOPY Objective: 1. To learn how to use both a dissecting and a compound microscope effectively and efficiently (lighting‚ focus‚ magnification‚ resolution)‚ and to practice manipulating small organisms Principals: 1. The smallest object viewable under a compound light microscope is limited by resolution or resolving power (ability to distinguish between two nearby points) and not magnification. 2. Mircoscope resolution is limited by the wavelength of the source of illumination (visible

‚ Tim Seitzer 11/1/10 Art Jan Verneer “Woman Holding a Balance” Light is used to draw your attention towards the woman holding the scale. The painting itself is asymmetrically balanced‚ drawing the viewers eye toward the “large” visually weighted bright object on the right distracting them from the darkness in the left. It seems that when one draws an oblique line from the top left corner to the bottom right corner‚ the light and darkness are almost evenly divided even though this draws

Imagine a set of binoculars; with two small peep holes for your eyes to see through and two larger lenses which magnify whatever it is that one may be looking at. Now there are two types of people in the world‚ one who looks through the small lenses and views the bigger picture‚ and one who takes a look through the bigger lenses to see a more narrowed finding. Those who see the bigger picture will have a different perspective than those who choose to look at the narrow view as will their beliefs

Chapter 1 Introduction 1.1 History of Free Space Optics Even though fibre-optic communications gained worldwide acceptance in the telecommunication industry‚ FSO communications is still considered relatively new. But optical communication‚ in various forms‚ has been used for thousands of years. The Ancient Greeks polished their shields to send signals during battle. In the modern era‚ semaphores and wireless solar telegraphs called heliographs were developed‚ using coded signals to communicate

POB II: Exam II Review Chapter 6: tour of the cell Microscopy: • Microscopes provide a window to the cell. • Most important tool in cytology • Resolution has improved understanding of cells. o Resolving power – the smallest distance between two objects that allows them to be seen as distinct objects. o Resolving power of the human eye is 0.1 mm • Light microscope – uses glass lenses and visible light to form a magnified image of an object. o Resolving power of about 100 nm (.0002 mm)
