Introduction! ! The Michelson Interferometer is commonly used to determine the wavelength of light or measure very small distances. It was invented by Albert Abraham Michelson and is commonly used in optical interferometry‚ a branch of physics involving a family of techniques one could use to extract information about waves by superimposing them. ! ! The original application of the Michelson Interferometer was to the famous Michelson-Morley experiment in 1887. Prior to Einstein’s

the spectrophotometer is to measure the concentration of solute. The solute being measured must be colored and is determined based on the adsorption of light photons on a wavelength. The spectrophotometer uses a beam of light that strikes the diffraction grating that basically forms of prism of light. Then only a specific wavelength of light shines through the spectrophotometer and interacts with the solute. The light that continues past the solute hits the phototube. The spectrophotometer then

Wave Nature of Light Objective: The purpose of this lab is to investigate interference‚ otherwise known as the diffraction of light. A beam of light acts a wave‚ and we are able to use equations so calculate the wavelength of the light used. The diffraction of a straight edge demonstrates that light waves bend around straight edges‚ allowing light to enter an area of shadow. When waves are superposed‚ they reinforce each other when crests are in phase and cancel out when they are not in phase

Investigatory Projects in Physics | Repulsorlifts as a Method of Stable Magnetic Levitation | Repulsorlifts were used in the study to find out if they can be used to replace the wheels of a conventional car. It was hypothesized that it will be able to lift a car using magnetic repulsion forces. The different magnets were tested individually with the usual tests for magnetic strength‚ size‚ and temperature increase‚ which were done in the preliminary testing. The prototype road and car were

In the introduction there is a more elaborated theoretical framework of previous research and an explanation of why “However‚ this coloration principle lacks homogeneous color brightness‚ since the nanogratings efficiency will vary for different diffraction angles.” (Ionin‚ Kudryashov‚ Makarov‚ & Seleznev‚ 2012) And how “spatial

It is important to study the polymorphic changes of the drug as these changes may influence dissolution rate and bioavailability of the drug. X-ray powder diffraction measurements were performed on samples utilizing a diffractometer. The results were recorded over a range of 0 –50° (2θ) using the Xe-filled detector and Cu-target X-ray tube. For characterization of crystalline state‚ XRD patterns for pure Zolmitriptan

XRD – X-Ray Diffraction X-ray diffraction (XRD) is a powerful non-destructive technique for characterizing crystalline materials. It provides information on structures‚ phases‚ preferred crystal orientations (texture)‚ and other structural parameters‚ such as average grain size‚ crystallinity‚ strain‚ and crystal defects. X-ray diffraction peaks are produced by constructive interference of a monochromatic beam of X-rays scattered at specific angles from each set of lattice planes in a sample. The
