What symbol represents a photon?
A photon is typically represented by the symbol ( \gamma ) (gamma) in the context of electromagnetic radiation. However, in quantum mechanics and particle physics, it is often denoted by the symbol ( \hbar ) in conjunction with energy equations, where ( \hbar ) is the reduced Planck's constant. Additionally, the notation ( \nu ) (nu) is used to represent the frequency of a photon in various equations.
States that is imposible to know both the velocity and the position of a particle at the same time?
The heisenberg uncertainty principle is what you are thinking of. However, the relation you asked about does not exist. Most formalisms claim it as (uncertainty of position)(uncertainty of momentum) >= hbar/2. There is a somewhat more obscure and less useful relation (uncertainty of time)(uncertainty of energy) >= hbar/2. But in this relation the term of uncertainty of time is not so straightforward (but it does have an interesting meaning).
What is a quantum state and what is a quantum fluctuation?
A quantum state is exactly as it sounds. It is the state in which a system is prepared. For example, one could say they have a system of particles and at time, t=(some number), the particles are at position qi (qi is a generalized coordinate) and have a momentum, p=(some number). You then know the state of the system. There are other properties that can be know for a particle. You could create a system of particles with a particular angular momentum or spin, etcetera. - A quantum fluctuation arises from Heisenberg's uncertainty principle which is \delta E times \delta t is greater than or equal to \hbar and it is defined as the temporary change in the amount of energy in a point of space. This temporary change of energy only happens on a small time scale and leads to a break in energy conservation which then leads to the creation of what are called virtual particles.
Why is bohrs model accurate?
Bohr's model is considered accurate for hydrogen-like atoms because it successfully explains the quantized nature of electron orbits, predicting specific energy levels and spectral lines. It incorporates the principles of quantization, where electron angular momentum is restricted to integer multiples of ( \hbar ). Additionally, it provides a clear understanding of the transitions between energy levels, which correspond to the emission or absorption of photons at specific wavelengths. However, its limitations arise for multi-electron atoms, where electron-electron interactions complicate the model's applicability.
Why time isn't an operator in quantum mechanics?
Associated with each measurable parameter in a physical system is a quantum mechanical operator. Now although not explicitly a time operator the Hamiltonian operator generates the time evolution of the wavefunction in the form H*(Psi)=i*hbar(d/dt)*(Psi), where Psi is a function of both space and time. Also I don't believe that in the formulation of quantum mechanics (QM) time appears as a parameter, not as a dynamical variable. Also, if time were an operator what would be the eigenvalues and eigenvectors of such an operator? Note:A dynamical time operator has been proposed in relativistic quantum mechanics. A paper I found on the topic is; Zhi-Yong Wang and Cai-Dong Xiong , "Relativistic free-motion time-of-arrival", J. Phys. A: Math. Theor. 40 1987 - 1905(2007)
