Refractive index

Lambert’s law. The individual particles of analyte no longer act independently of each other at higher concentration. The 2nd contribution is that the analyte’s absoptivity rely on the refractive index of sample. As refractive index changes with the analyte’s concentration, the value of ε and a may change. The refractive index is necessarily constant and the caliberation curve is linear, for sufficiently low concentration of analyte. Chemical limitations to beer’s law A chemical deviation may…

and its global market Moissanite is used as an alternative to diamond jewellery. It is regarded at par with diamond when compared on the basis of quality and physical properties. Moreover, moissanite glitter more than diamond due to a higher refractive index and is as hard as diamond. A layman may barely distinguish between the two and mostly a distinction can be drawn through a laboratory test. However, the moissanite jewellery is cheaper in comparison to diamond and this makes it a better…

Characterizing the IR Reflecting Properties of Pigments for Cool Roofs Introduction The sun energy reaches earth as UV visible and Infra-red radiation. UV radiation is an invisible part of electromagnetic spectrum. Only 5 % UV from sun reached the surface is play the major role to the degradation of coating .Visible light wave (295-400 nm) seen by human eyes. Around 50% of the suns energy occurs in this region which gives the perception of colour.45 % of total solar energy is in IR region…

Background Since 2001 there have been 2372 American military deaths and 17674 documented injuries from war3. In each division of the United States Military, there are numerous injuries that occur each month. Some injuries are a result of training incidents or equipment failure, however, most injuries are due to attacks on troops. Some of these injuries, when not treated immediately, lead to lifelong physical or mental damage, or even death. While on the battlefield, immediate and proper medical…

In the video game Halo, Promethean Vision enables the players to look through solid walls at an object. At first glance, the properties of light as it interacts with most common materials may make this concept seem impossible to recreate in real life. However, by looking further into the physics of optics, the concept of see-through vision may not need to be confined solely to science fiction. Indeed, this technology may be replicable in the real world, to a limited extent, though it may not…

Indeed, this is essential to the foundation of all forensic labs (Dale and Becker 173). Forensic scientists use electrophoresis gel to prepare and differentiate fingerprints (Bertino 165). Which is then uploaded to the Combined DNA Index System (CODIS). Allowing access to registered crime lab officials to share and compare DNA profiles (Dale and Becker 176). Sharing this information aids police investigations as mitochondrial DNA can be extracted from fragments of bone and compared to maternal…

Physiochemical Characterization of Microemulsion:- 5.1 Determination of Droplet size distribution and zeta potential Droplet size distribution, polydispersity index and zeta potential of the resultant microemulsion was determined immediately using, Nano Malvern droplet analyzer (UK) and zeta potential analyzer. Wavelength scattering angle 90º at 25ºC, average hydrodynamic diameter of the microemulsion was derived…

Zinc is an important dietary component in human beings and animals. Although not considered hazardous, overdose of Zinc may cause nausea, vomiting, dizziness, colics, fevers and diarrhea and if it exceeds a certain limit it may also prove to be toxic. Zinc, present in natural water in small concentration, most commonly enters the domestic water supply from deterioration of galvanized iron and dezincification of brass[1,2]. Industrial and household waste, discharges directly or indirectly through…

model (discussed in subsection 2.2.5) which uses a transport equation for G, the Rosseland model assumes that the incident radiation intensity is the black body intensity at that temperature of the medium. In other words [3], (2.14) where n is refractive…
