Pulsar: Any of several celestial radio sources emitting short intense bursts of radio waves‚ x-rays‚ or visible electromagnetic radiation at regular intervals‚ generally believed to be rotating neutron stars. Quasar: An extremely distant‚ and thus old‚ celestial object whose power output is several thousand times that of our entire galaxy. Black Hole: An area of space-time

Chromatography of Photosynthetic Pigments Abstract In this experiment a process of chromatography was used to separate chlorophyll a‚ chlorophyll b‚ xanthophyll‚ and beta carotene. When these pigments were obtained they were used to measure the wavelengths by way of spectrophotometer of each and the total of all the pigments wavelength. Introduction Photosynthesis is a process by which plants use the sunlight to convert it from light energy into chemical energy. This equation shows us how

So 1 A Only absorbed quanta can realize photochemical impact and the reader should remember that a spectral region of a photobiological process is conditioned by the absorption spectrum of a substance involved in this process. The extinction law for actinic monochromatic light absorbed by a substance layer can be written in the exponential or logarithmic form: I ¼ I0 Á 10ÀeCd ; V.S.

experiment‚ Δ/Λ-[Co(en)3]Cl3∙4H2O was synthesized and the absorbance in UV-vis spectrum was recorded. Δ/Λ-[Co(en)3]Cl3∙4H2O has an εmax of 197.33 mol–1dm3cm at 466.00nm and 210.39mol–1dm3cm-1 at 338.00nm. and the colour of the crystals obtained were orange. The crude product was then reacted with L-(+)-tartaric acid and 0.59g of the enantiomer [Λ-Co(en)3][(+)-tart]Cl∙5H2O was obtained. FT-IR spectroscopy was performed and the spectrum was analyzed. Green crystals of trans-[Co(en)2Cl2]Cl∙HCl∙2H2O was also

Discussion Questions 1. 2. What is a spectroscope and what is it used for? A spectroscope is a scientific instrument that is used to measure the intensity of the light at different wavelengths by calculating the amount of light energy that is being absorbed by the electrons at different wavelengths. 3. 4. 6. How might the difference in the brightness of spectral lines be explained? In other words‚ why are some lines in a spectra easier to see and appear brighter? Some lines in a spectra are easier

established various ways to utilize infrared light. Infrared absorption spectroscopy is the method which scientists use to determine the structures of molecules with the molecules’ characteristic absorption of infrared radiation. Infrared spectrum is molecular vibrational spectrum. When exposed to infrared radiation‚ sample molecules selectively absorb radiation of specific wavelengths which causes the change of dipole moment of sample molecules. Consequently‚ the vibrational energy levels of sample molecules

1. i) • Antenna radiation pattern or antenna pattern is defined as “a mathematical function or a graphical representation of the radiation properties of the antenna as a function of space coordinates.” • The radiation pattern is determined in the far-field region and is represented as a function of the directional coordinates. • Radiation properties include power flux density‚ radiation intensity‚ field strength‚ directivity phase or polarization [pic]

Before beginning our research on radio waves‚ to us‚ radio waves were just waves going through the atmosphere‚ carrying sound from one place to another. Those were our ignorant days! We did not realize the complicated terms and theories involved. In the following report you will see how we advanced in our knowledge of radio waves‚ and we hope it will do the same for you. Radio waves are a combination of two kinds of electric vibrations. Audio frequency waves‚ which represent voice and other

Firefighters. How can we help them be safe and keep them healthy for their everyday lives? Well we should all know that fire fighters have an important job not only for themselves but for the community basically. They respond to emergency situations and protect people‚ from accidents‚ sickness‚ or things like fires that can cause harm or even sadly a loss of a family member. To get fire fighters better protected and safe I think that they shouldn’t have to wear all that heavy gear because if they
