Due to technical potential of 5‚000 trillion kWh per year and minimum operating cost‚ Solar Power is considered the best suited energy source for India. Today the Solar power‚ has

1. Forward Biased LED- A process when a positive voltage is applied to the p region and a negative voltage to the n region. 2. Incoherent Light- Light in which the electric and magnetic fields of photons are completely random in orientation. Typically emitted from light bulbs and LEDs. 3. Laser-(light amplification by stimulated emission of radiation) used to provide the high-powered‚ tightly controlled light wavelengths necessary for high-speed‚ long-distance optical fiber transmission. 4.

Hird1 & Seth J. Putterman1 Relative motion between two contacting surfaces can produce visible light‚ called triboluminescence1. This concentration of diffuse mechanical energy into electromagnetic radiation has previously been observed to extend even to X-ray energies2. Here we report that peeling

investigate the size and shape of particles. These range from basic (generally older) techniques such as sieving and use of optical microscopes through to more advanced techniques‚ such as using a coulter counter‚ a scanning electron microscope or photon cross correlation spectroscopy. You will cover a range of techniques in the lectures that accompany this section of the module and you should refer to your lecture notes for further details. The aim of this practical is to examine different techniques

Theory CONDUCTORS‚ INSULATORS AND CONDUCTIVITY Conduction of electricity in electric circuits takes place due to the presence of excess electrons in materials called conductors. Electrons move in the direction in which the potential has been applied. The ability of a conductor to conduct electricity is directly proportional to the material’s area of cross section and inversely proportional to its length. Where‚ G is conductance σ is conductivity A is area of cross section

which released the most amount of energy‚ is potassium nitrate. Because the amount of energy light produces is depended on the frequency (colour) of the light‚ and potassium nitrate produced a light purple colour. According to the visible spectrum‚ a photon of purple had more energy than any other colour produced in this lab‚ because purple light has shorter wavelength (approximately 380-450 nm) and shorter wavelength means higher frequency which also means higher energy. Therefore we can conclude that

Oil‚ or petroleum‚ is one of the most common fossil fuels utilized by people all over the world on a daily basis. Crude oil is a smelly‚ yellow-black‚ viscous liquid composed of mostly nitrogen‚ oxygen‚ and sulfur‚ which is

protons and electrons recombine‚ the electrons enter a higher energy level (n=3). Then‚ when the electron drops from the n=3 level to the n=2 level‚ an Hphoton is emitted. 2 This photon has a wavelength of 6563 Å‚ and therefore corresponds to the red portion of the visible spectrum. It is these H photons which give the nebula the distinctive red color which we see. The extreme brightness of the O-type and B-type stars‚ coupled with the Earth’s atmosphere‚ has always made

spectrophotometer measures the amount of light that a solution absorbs. This is done by bombarding the sample with a beam of light of known intensity. Basically‚ this beam is composed of photons that the sample may absorb. As a consequence‚ the pre-assembled light detector in the machine receives less number of photons. The transmittance (T) relates this detected light intensity (P) to the incident one (Po) by the equation T = P / P0 (1) It should be noted that transmittance simply dictates the
