    cName: Nicholas Cassel Gen Chem 1210 23 March 2013 Blinded By the Light Abstract: In this experiment we were provided a cereal box spectrometer to observe the emission lines of noble gases and hydrogen. Based on the scale readings on the spectrometer and the Balmer-Rydberg formula‚ their wavelengths and percent error were able to be extrapolated. Based on the literature values‚ the cereal box spectrometer proved its value as a decently accurate spectrometer. Introduction: Every element

    place and the chamber lid is closed‚ light from the light bulb passes through it. The detector measures the amount of light transmitted. The white light from the bulb is separated into different wavelengths by reflecting the beam off of a diffraction grating‚ forming a spectrum. A mirror is used to control the angle at which the light is reflected‚ so light of a single wavelength can be passed through the sample. A pigment solution (such as spinach and acetone) is exposed to different wavelengths

    Newton’s Laws of Motion and Gravity Define mass‚ weight‚ force‚ and acceleration. Mass – A measure of the total amount of material in a body‚ defined either by the inertial properties of the body or by its gravitational influence on other bodies. It is proportional to‚ but not the same as‚ its mass Force – A quantitative description of the interaction between two physical bodies‚ such as an object and its environment. Force is proportional to acceleration. Acceleration – A vector quantity that

    Experiment 2: Starch Hydrolysis by Amylase Theoretical Background Polymers of carbohydrates are called polysaccharides‚ and make up some of the most important naturally occurring compounds [1]. They have thousands of monosaccharide units linked to each other by oxygen bridges. They include starch‚ glycogen‚ and cellulose‚ all three of which yield only glucose when completely hydrolyzed [2].

    NUS/ECE EE4101 Antenna Arrays 1 Introduction Antenna arrays are becoming increasingly important in wireless communications. Advantages of using antenna arrays: 1. They can provide the capability of a steerable beam (radiation direction change) as in smart antennas. 2. They can provide a high gain (array gain) by using simple antenna elements. 3. They provide a diversity gain in multipath signal reception. 4. They enable array signal processing. Hon Tat Hui 1 Antenna Arrays NUS/ECE

    Chargaff’s rules‚ X-ray diffraction studies‚ and the use of brass and wire models of sugars‚ and phosphate groups. This revelation contributed heavily to scientific research and studies. They deduced that from their studies that DNA is structured in a Double Helix. With all of the evidence they accumulated they were able to achieve as well as build something great‚ with such a huge impact on the world. One piece of evidence they used to determine the structure of DNA was X-ray diffraction studies. X-ray

    Virtual Retinal Display Seminar Report 2004 Abstract The Virtual Retinal Display (VRD) is a personal display device under development at the University of Washington ’s Human Interface Technology Laboratory in Seattle‚ Washington USA. The VRD scans light directly onto the viewer ’s retina. The viewer perceives a wide field of view image. Because the VRD scans light directly on the retina‚ the VRD is not a screen based technology. The VRD was invented at the University of Washington in the
