一道英文的物理题When a proton captures an electron,a photon with anenergy of 13.6 eV is emitted.What is the frequency of thisphoton?Does it lie in,above,or below the visible range?答案 当一个质子捕获一个电子时,会发射出一个具有13.6电子伏能量的光子,请问这个光子的频率是多少?它是否在可见光...
Fluorescence is a type of luminescence, a process where energy is released from a chemical compound via the emission of a photon. This process happens through the transition of electrons between energy levels. Electron transitions Which energy levels electrons move between governs the type of transiti...
What is released when an electron loses energy? Energy: Atoms absorb and lose energy. Generally, it's the electrons that absorb and lose energy. The energy absorbed by an electron in the first energy level making it jump up to the next energy level is 10.2 electron-volts (eV). ...
If you look closely at what happens as the light wave enters the prism in the second diagram, you will notice that it bends down. This bending occurs because the light travels faster through the air than it does through the prism. When the lower portion of the wave enters the prism, it...
What happens when 2 photons collide? However, two photons heading towards each other can indeed collide indirectly. ... A photoncan spontaneously degenerate into a particle with mass and its antiparticlein a process known as pair production. In this process, the energy of the photon is complete...
According to Bohr's model, what happens to the electron when a hydrogen atom absorbs a photon of light of sufficient energy? How is the Bohr theory of the hydrogen atom inconsistent with the uncertainty principle? Using what you know about the Bohr ...
What happens when we think that others expect us to fail? My research shows that these “underdog expectations” can actually motivate (激励) people to try to prove others wrong, especially those they find less trustworthy, — leading them to perform better. I conducted an experiment asking ...
He said, “I understand that they say that light is emitted from an atom when it goes from one state to another, from an excited state to a state of lower energy. I said, “That’s right.” “And light is a kind of particle, a photon, I think they call it.” ...
What happens to radiant energy once it enters the atmosphere? What type of electromagnetic waves are emitted from the sun? Which type of electromagnetic radiation is lowest in energy? What produces electricity from a magnetic field? Sunlight is a form of energy called ...
Recently, a number of techniques have been developed to support the molecular imaging of cancer stem cells. While some research is focused on the in vivo identification of CSCs via functional imaging through positron emission tomography (PET), single photon emission tomography (SPECT), or magnetic ...
