Light Emission and Absorption - Active Reading When atoms absorb energy‚ electrons can jump to higher energy orbitals. When the electrons move back to their original configurations‚ that energy is given off as light! Travel to the website linked below and take Cornell notes for each section. Write some big ideas in the left column and supporting details in the right column. Make sure to answer any questions given as well. Make sure you play and watch every animation and click every link

A parabolic antenna for Erdfunkstelle Raisting‚ based in Raisting‚ Bavaria‚ Germany. To direct microwaves in narrow beams for point-to-point communication links or radiolocation (radar)‚ a parabolic antenna is usually used. This is an antenna that uses a parabolic reflector to direct the microwaves. To achieve narrow beamwidths‚ the reflector must be much larger than the wavelength of the radio waves. The relatively short wavelength of microwaves allows reasonably sized dishes to exhibit the desired

Spectrophotometry/Beer’s Law Lecture Chemistry 114 Overview: Spectroscopy will be a tool that you will use as you continue in your chemistry‚ biology and physics courses. Already‚ you have used spectroscopy in this course and CHM 113. Earlier in the term‚ we used the spectrophotometer to monitor double stranded and single stranded DNA. We have also used it to measure concentration of chemicals. This lecture will discuss spectophotometry in more detail. Background: You will recall from

Determining the concentration of red dye #40 in an unknown solution Introduction: White light is composed of many different wavelengths of light combined together. A spectrophotometer is an instrument that shines a single wavelength of light of a known intensity into a solution and then measures the intensity of the light exiting the solution. If a solution contains

Investigation: 20 How much cobalt is in the soil? Introduction: By completion of investigation 20‚ a standard curve of absorbance versus known cobalt (II) nitrate was prepared. The concentration of cobalt (II) ion obtained from a soil sample was determined. Whether or not cobalt nitrate should be added to the soil was determined. If cobalt nitrate needs to be added‚ then how much will it be required to meet the necessary nutritional needs of the animals was established. In colorimetry

Flame Test Lab - Post Lab Questions and Pre-Lab Questions Pre-Lab Questions: 1.When an atom absorbs energy‚ the electrons move from their normal state to an excited state. When an atom emits energy‚ the electrons move from an excited state to their ground state and give off photons. 2.Is the flame test a qunatitative test or qualitative test for the identity of an unknown? This flame test is both quantitative and qualitative. It is quantitative because we are measuring the wavelength

Implementation of a Chirped Pulse Fourier Transform Microwave (CP-FTMW) Spectrometer Abstract: Under the condition in which electric and magnetic fields are absent‚ rotational constants is a three molecular constants that substantiate polyatomic molecule. In this laboratory experiment at Missouri University of Science and Technology‚ we are going to collect rotational spectra by using 2 separate types of microwave spectrometers -- the FTMW (Fourier Transform Microwave) spectrometer and CP-FTMW
