Electromagnetic Radiation: Emission of EMR (Electro-Magnetic Radiation) occurs from every substance. This is due to transition of electrons from one energy state to the other‚ leading to emission of radiation at discrete wavelengths‚ thus resulting into line spectrum. The wavelengths‚ which are emitted by atoms‚ are also the ones‚ which are absorbed by them. Emission from solids and liquids occurs when they are heated and results in a continuous spectrum. This is called Thermal Emission and it is an

Young’s double slits Formal Lab Florencia Shi Purpose: The double slits experiment was conducted to observe the interference of light waves‚ to explore how interference pattern would be affected by different colours‚ and to determine whether interference would change if the angle of slits was changed horizontally or vertically. Hypothesis: Dark and light bands would be seen‚ and red light causes wider nodal spacing‚ while blue light causes shorter nodal spacing. Materials: In this experiment

or higher) determines the wavelengths at which light is absorbed. Absorption (excitation) can result in a range of transitions to various vibrational sublevels of excited singlet states‚ which is then followed by nonradiative relaxation to the lowest sublevel of the S 1 state‚ via vibrational relaxation and internal conversion. Internal conversion‚ singlet–triplet intersystem crossing and fluorescence then compete for relaxation to the ground state (S 0). The wavelength of the fluorescence emission

chloroplasts To test absorption of isolated chloroplasts from spinach absorption readings were taken at a series of different wavelengths. Absorption Maxima of the isolated chloroplasts were observed at wavelengths of 440 and 680 with corresponding absorbance values of 0.792 and 0.589 were noted (Fig 1.). Absorption minima of the isolated chloroplasts was noted at a wavelength of 580 at an absorption of 0.291 (Fig 1.). This indicated that green light is reflected strongly by the spinach pigment.

Particle in a Box Lab March 25‚ 2014 Kassandra Brady‚ Samantha Imler‚ & Michael Montone CHEM 353 Abstract: Introduction: Method I: Absorption Spectra of Conjugated Dyes This method analyzes a series of dyes with alternating double bonds. It is assumed that the π electrons are free to move and ignoring the electro static repulsion among the π electrons themselves. The theoretical model applied in this experiment is the particle in the box. The model states that a single particle moves free

therefore they do not need a medium (substance) to propagate (move). 2. identify the electromagnetic wavebands filtered out by the atmosphere‚ especially UV‚ X- rays and gamma rays The electromagnetic spectrum is spit up by varying wavelengths‚ long wavelengths are radio waves‚ and short ones are gamma rays. This is shown in the diagram below. Fig. (4) The EMR (Electromagnetic Spectrum) Earth’s atmosphere filters out most of the electromagnetic waves except for visible light and radio waves
