 Quantum Wells,and Examples or application of Quantum Wells. The classic model used to demonstrate a quantum well is to confine particles, which were initially free to move in three dimensions, to two dimensions, by forcing them to occupy a planar region. The effects of   quantam confinment   take place when the quantum well thickness becomes comparable to the   de Broglie wavelength   of the carriers (generally   electrons   and   holes ), leading to energy levels called "energy subbands", i.e., the carriers can only have discrete energy values. A wide variety of electronic quantum well devices have been developed based on the theory of quantum well systems. These devices have found applications in lasers, photodetectors, modulators, and switches for example. Compared to conventional devices, quantum well devices are much faster and operate much more economically and are a point of incredible importance to the technological and telecommunication industries. These quantum wel

 Why did Albert Einstein have so much difficulty accepting Quantum Mechanics? Albert Einstein one of the most famous physicist in the world and very much popular for mass-energy equivalence that is E = mc 2   Then  Why did Albert Einstein have so much difficulty accepting Quantum Mechanics? Quantum Mechanics is very vast subject to study and is very difficult to understand but in short we can conclude that Quantum Mechanics implies that a particle such as ELECTRON can pass through TWO HOLES AT ONE TIME READ ABOUT TOP 10 SOLAR PROJECTS OF INDIA His analysis of the "spookiness" of quantum mechanics opened up a whole range of applications including quantum teleportation and quantum cryptography, but he wasn't completely convinced by the theory of quantum mechanics – and that story is as fascinating as the theory he attempted to nail down. German physicist Erwin Schrödinger's equations proved that a cat could end up in a peculiar sort of quantum state, being neither dead

 Why do solar eclipses look like a black hole in the sky? What is meant by Eclipse  Any solid object in our solar system can cast a shadow by blocking the light by the region behind it. This shadow in the space becomes  apparent  whenever another object moves into it. In general an eclipse occurs whenever either part of Earth or Moon enters the shadow of other.  What is meant by solar eclipse When the Moon’s shadow strikes Earth, people within that shadow see the Sun at least partially covered by the Moon; that is, they witness a  solar eclipse . What is meant by Lunar Eclipse Lunar eclipses  occur when Earth's shadow blocks the sun's light, which otherwise reflects off the  moon . There are three types  total, partial and penumbral with the most dramatic being a total  lunar eclipse , in which Earth's shadow completely covers the  moon . black holes and types of black holes This means the Moon and the  Sun appear  exactly the same size in our  sky ! So, when the Moon lines

       what is the Science of a on grid solar ? First of all what is solar and what is solar energy Solar energy a great source of energy  and a perfect alternative for Coal and other source of energy. So what are the advantages of solar energy and how we can utilize the solar energy and related all questions are answered here India is endowed with vast solar energy potential. About 5,000 trillion kWh per year energy is incident over India's land area with most parts receiving 4-7 kWh per sq. m per day. Solar photovoltaics power can effectively be harnessed providing huge scalability in India. what is meant by Electrical Grid An  electrical grid ,  electric grid  or  power grid , is an interconnected network for delivering  electricity  from producers to consumers. It consists of: generating stations that produce  electric power .  electrical  substations for stepping  electrical  voltage up for transmission, or down for distribution Let us consider how does Solar panel works We al

 What will happen if a man will fall in the black hole  at the middle of our Milky Way galaxy? Let us consider first what is black hole     Black holes  are some of the strangest and most fascinating objects in outer space. They're extremely dense, with such strong gravitational attraction that even light cannot escape their grasp if it comes near enough. There are three types of black holes that known to scientist so far 1.Stellar black holes 2.Supermassive black holes 3.Intermidiate black holes out of these three black holes the supermassive Black Hole is present at the middle of each galaxy including ours the MILKY WAY GALAXY WHAT IS SUPERMASSIVE BLACK HOLE  Supermassive black holes are consider as the birth of Giants. As the name suggest supermassive black holes these are millions or even billions times  as massive as the sun, but they are same in the diameter. Such type of black holes are considered to found in the center of every galaxy including our galaxy Milky Way. Scient

what is photosynthesis ?  what is the role of chlorophyll in the preparation of food in plants ? what is meant by chlorophyll ? A green pigment , present in all green plants and in cyanobacteria, which is responsible for the absorption of light to provide energy for photosynthesis. Chlorophyll is located in a plant’s  chloroplast s, which are tiny structures in a plant’s cells. This is where photosynthesis takes place. Phytoplankton, the microscopic floating plants that form the basis of the entire marine food web, contain chlorophyll, which is why high phytoplankton concentrations can make water look green. CLICK HERE   Green plants have the ability to make their own food. They do this through a process called photosynthesis  which uses a green pigment  called chlorophyll . A pigment is a molecule that has a particular color and can absorb light at different wavelengths, depending on the color. There are many different types of pigments in nature, but chlorophyll is unique in its abil
