Quantitative Spectroscope And Visible Light Lab Report

The experiment used a light of a single color, or monochromatic light, and two closely spaced slits or pinholes. He realized that the bright fringes of light resulted from light waves from both holes arriving crest to crest, creating a constructive interference. He also realized that the dark areas resulted from light waves coming from trough to crest, creating a destructive interference. The interference fringes made were straight lines. This interference experiment demonstrated the wave nature of light idea generated by Huygens 200 years earlier.

Unit D Summary: Light and Geometric Optics 10.1 : Light and The Electromagnetic Spectrum Chapter 10.1 covers light and the electromagnetic spectrum. This chapter starts off by describing how light is a form of energy that travels in waves. The properties of said waves include a crest (the highest point of the wave), the trough (the lowest point of the wave), and the rest position (the level of a wave without energy).

PSY 350: Experimental Psychology Statistics planning worksheet 1. What is your conceptual IV? That is, what thing do you want to change for participants because you think it will affect an outcome? If you have more than one IV, answer this question for each IV separately. The conceptual independent variable is the emotions of the participants during the experiment. 2.

Doriana Spurrell What different frequencies and types of light would prompt the Spinach leaves to go through the process of photosynthesis effectively? Purpose: The purpose of this experiment was to see which of the four lights that range across the light spectrum would properly and most efficiently help the spinach leaf perform photosynthesis. Background Information: Photosynthesis is the process in which plants use light energy to transform into chemical energy.

This is where he noticed different spectral lines between the light emitted from the candle and the light emitted from the sun. This discovery led to his invention, the spectroscope. This new instrument allowed him to investigate the spectral lines of many light sources. These lines of absorption (the dark lines) became known as Fraunhofer lines. His knowledge on light diffraction of many types of glass was nearly unparalleled and helped him to build some of the most innovative refractive lensing technology of its

When an atom is heated the electrons jump to higher energy levels. Eventually they drop back down one or two or three levels emitting light energy. Each jump has a distinct package of energy and hence wavelength and thus produces a single line of the spectrum. A sodium street light is orange because it has 2 very strong orange lines as well as some fainter ones. How did the line emission spectrum lead to the Bohr Model of the Hydrogen Atom?

The different wavelengths of visible light (Randy M. Russell, Windows to the Universe,

Light Refraction Lab Final Write-Up When light passes through any obstacle, it is affected in different ways, especially when the obstacle is transparent. In this lab, the objective was to show students what happens when light passes through water. “When light refracts into a substance in which it must slow down, the light ray will bend toward a line perpendicular to the surface it strikes” (Wile). Water forces a light ray to slow down, and so the light ray will bend.

Three Foundational Aspects The Aurora Borealis is an amazing and wonder site to spectate for all ages and especially spectacular for photographers to capture that exact moment with all the different shades, but have you ever wondered why there are different colors? Where these extravagant pictures are taken? More well as why some pictures you see are clearly more visible and vibrant than others. In these short essay I will discuss the science behind all these questions. What makes different colors?

Spectral lines are a bright line resulting from emissions of light in a very narrow frequency range. These lines are very strong radio emission lines. A light curve in AGN in simple terms means brightness verse time. Brightness

The absorbance level @ 520 nm obtained from the spectrometer indicates the amount of urea obtained via measuring the absorbance of the light through the supernatant coloration, which was provided by the

In xxx I experimented with light reflecting on the surface of the water in a sea cave and how it shimmers on the rocks and other

[3] This pattern is also linked to Equations 1&2 as stated previously. The position of every fourth fringe was recorded giving the value which is required in Equation 3 below. (See Table1 for the recorded data) Knowing the wavelength of sodium to be 589nm the angle, ,at the apex between the two glass plates can be calculated using Equation 3 as

Hyperspectral Imaging “If a picture is worth 1000 words, a Hyperspectral image is worth almost 1000 pictures.” Dr. John P Ferguson Hyperspectral imagining by definition means obtaining the spectrum for each pixel in the image of a scene, with the purpose of finding objects, identifying materials, or detecting processes. In more scientific terms, imaging spectroscopy (another terminology for Hyperspectral imaging) measures the spectral signatures hence allows it to measure the chemical composition of all features inside the sensor’s field of view. In simpler terms Hyperspectral imaging allows the identification of certain materials and/or elements from a specific image using both spatial and spectral information from the materials within a
