    Questions and Pre-Lab Questions Pre-Lab Questions: 1.When an atom absorbs energy‚ the electrons move from their normal state to an excited state. When an atom emits energy‚ the electrons move from an excited state to their ground state and give off photons. 2.Is the flame test a qunatitative test or qualitative test for the identity of an unknown? This flame test is both quantitative and qualitative. It is quantitative because we are measuring the wavelength‚ and it is qualitative because we

    scientists looked at the world and set a foundation for modern inventions. For E=mc2‚ it one of the equations the helped the Theory of Relativity. For the foundation for modern physics‚ it helped lead onto other modern physics discoveries such as Photons‚ Bose-Einstein Condensate‚ and the Atomic Bomb. Life without this knowledge is like a life without living. As you can see‚ without Einstein’s discoveries‚ loads of other pieces of modern physics would not have been found. And finally‚ how did he

    release some energy – which it does in the form of a photon. The energy level of this photon corresponds to how far the electron dropped between orbitals. So when a photon collides with another atom‚ the energy in the photon sometimes gets absorbed and boosts an electron in that atom to a higher level‚ but only if the amount of energy in the photon (from the 1st electrons drop) matches the energy required to boost the 2nd electron. Otherwise‚ the photon will not shift electrons between orbitals. That

    atoms of a metal into a flame‚ electrons can be induced to absorb energy and jump to an excited energy state‚ this is called a quantum jump. They then return to their ground state by emitting a photon of light. The amount of energy in the photon of light determines its color. For example‚ when a photon gives off red light‚ you can determine that it does not have a lot of energy because red light is the lowest of visible light on the electromagnetic spectrum. Opposite to that‚ violet light would

    Green Computing: Should It Be Photonics or Spintronics for Quantum Computers? Xavier Mattam xaviermattam@hotmail.com Abstract - Quantum Computers are widely acclaimed as the future computers. There is so much research being done in this field of Quantum Computers that one would rightly feel that the advent of Quantum Computers for everyday use is not far off. But at a time when Global Warming has become a real threat to our very existence‚ the question we need to responsibly ask ourselves before

The wavelength of a photon and De-Broglie wavelength of an electron have the same value. Show that the energy of the photon is ( 2mcλ ) / h times the kinetic energy of the electron. Q.5. Electrons are emitted from a photosensitive surface when it is illuminated by green light but electron emission does not take place

    radiation‚ such as visible light‚ that is above the threshold frequency. This is because electrons cannot get enough energy to overcome their atomic bonding. The photoelectric effect furthered wave particle duality‚ whereby physical systems (i.e.: photons in this case) can display both wave - like and particle – like properties and behaviours‚ a concept used by the creators of quantum mechanics. It was explained mathematically by Einstein‚ utilising work in quantum mechanics‚ and was developed by people

    Introduction The Quantum Theory was the second of two theories which drastically changed the way we look at our physical world today‚ the first being Einstein’s Theory of Relativity. Although both theories revolutionized the world of physics‚ the Quantum Theory required a period of over three decades to develop‚ while the Special Theory of Relativity was created in a single year. The development of the Quantum Theory began in 1887 when a German physicist‚ Heinrich Hertz‚ was testing Maxwell’s
