gives a whole new meaning to the term “networking”. It is a new personal area networks technology which uses the surface of the human body‚ as a safe data transmission path‚ at speeds up to 10 Mbps. Red Tacton does not rely on electromagnetic or a light wave to transmit data. It makes use of weak electric fields on the surface of the body. Using a new super-sensitive photonic electric field sensor‚ it can achieve duplex communication over the human body. The Red Tacton chips‚ which

What is the Chemical Basis of Colour in Fireworks? Abstract: The purpose of the first experiment was to see the light spectra of different elements‚ and confirm that each element shows unique emission spectra‚ in terms of being able to identify an unknown substance. The analysis is expected to show that elements do indeed have unique emission spectra‚ allowing elements to be identified by their emission spectra. After burning different chemicals under a Bunsen burner‚ the colourful light was

A Spectrophotometric Analysis of the Absorption of Green Light Versus Red Light Absorption in Spinach Leaves The goal of the experiment was to determine if green light had less ability to absorb than red light in spinach leaves. This was done by separating the photosynthetic pigments (chlorophyll a‚ chlorophyll b‚ carotene and xanthophylls) from one another using paper chromatography. The separated pigments were then analyzed for their absorption spectrum using a spectrographometer. When the

Lesson 1 Key Question Answers 1. What does Hubble’s law predict about the speed of a galaxy far away from the Milky Way compared to one that is closer? Hubble’s law predicted that galaxies were moving away from earth at a rate proportional to their distance from us. The farther away from the Milky Way a galaxy is‚ the larger the redshift is. The farther away a galaxy is‚ the faster it is moving away. Conversely‚ blueshifted galaxies‚ such as Andromeda‚ are moving closer to the Milky Way.

light visibility. This means that everywhere where LEDs are used‚ lighting bulbs can bring not only the light but wireless connection at the same time. With increasing demand for wireless data‚ lack of radio spectrum and issues with hazardous electromagnetic pollution‚ Li-Fi appears as a new greener‚ healthier and cheaper alternative to Wi-Fi. Moreover Li-Fi makes possible to have a wireless Internet in specific environments (hospitals‚ airplanes etc.) where Wi-Fi is not allowed due to interferences

integer positive quantum number‚ h is Planck’s constant‚ m is the mass of the particle and L is the length of the box. If we assume that the most intense band in the experimentally observed spectrum can be interpreted as absorption of electromagnetic radiation by an electron as it is promoted from the HOMO to the LUMO‚ we can derive the following expression for the energy absorption E. E =h2 [2ni+ 1]/ (8mL²) (2) the absorption
