INFRARED COMMUNICATION

Have you ever wondered how your TV remote works? How is that you are able to switch channels being seated at a place? It is always so fascinating to learn about the devices you use in daily life, isn’t it? The link between the TV and the remote is the infrared rays.

And thus veins carry blue blood. But the fact is that the veins carrying deoxygenated blood appears blue from the skin surface. Light from outside illuminates veins to appear light through the layers of skin. It is not the colour of blood which is blue. The fact is oxygenated blood is dark red in colour and the deoxygenated appears a little lighter red than the oxygenated blood.

ELECTRO MAGNETIC INDUCTION

What is EMI? EMI is a phenomenon in which an electric current or electromotive force is induced in the coil due to a magnetic field produced in the coil. Michael Faraday is the scientist behind the invention of electromagnetic induction. Though Faraday was first to publish this but it was discovered autonomously by Joseph Henry. This electromagnetic induction is dependent on Faradays Laws of a magnetic field. Faraday first proved this electromagnetic theory by winding copper wires to both ends of the iron rod. He explained this theory using a concept of lines of force. What is Faradays experiment? Faraday

BLUETOOTH TECHNOLOGY

Bluetooth is one of the wireless technologies for the sharing of data over short distances. This short link service using radiowaves was initiated by Nils Rydbeck CTO at Ericson mobile in Lund. In 1998 the Bluetooth technology was adapted and it kept on evolving to date.  Bluetooth is managed by Bluetooth Special Interest Group (SIG). The data transmission was done using the radio waves of ISM band 2.4 to 2.485GHz.   Even before we get to know how Bluetooth functions let’s see its timeline of evolution from the time of its invention to date. 1998: The research was completed and

Layer of Earth ASTHENOSPHERE !!

ASTHENOSPHERE The asthenosphere is one of the layers of earth lying below the lithosphere, approximately 80 to 200km beneath the earth’s surface and is a part of the upper mantle. It is made up of a layer of solid rocks. It has so much of pressure and heat that these solid rocks just flow down like liquids. These asthenosphere rocks are less dense than the lithosphere. This factor accounts for the movement of tectonic plates in the lithosphere to move on the earth’s surface. The temperature defines the thickness of the asthenosphere layer. As the temperature increases, the pressure exerted
