The transition probability, l, is also called the decay probability and is related to the mean lifetime t of the state by l = 1/t. The general form of Fermi's golden rule can apply to atomic transitions, nuclear decay, or scattering.

Quantum mechanics explains transition probability through the concept of wave functions, which describe the probability distribution of finding a particle in a given state. When a system undergoes a transition from one state to another, the transition probability is related to the overlap between the initial and final wave functions of the system. This overlap determines the likelihood of the transition occurring.

Why the concept of trajectory is meaningless in quantum mechanics?
In quantum mechanics, particles like electrons do not have well-defined trajectories as they do in classical mechanics. This is due to the principle of wave-particle duality, where particles exhibit both wave-like and particle-like behaviors. Instead of following a specific trajectory, we describe the behavior of particles in terms of probability distributions determined by the wave function.
Which model of the atom states that the position and location of an electron cannot be known with certainty but only stated as a probability?
The quantum mechanical model of the atom, also known as the electron cloud model, states that the position and location of an electron cannot be precisely determined but rather described in terms of a probability distribution within an atomic orbital. This model was developed based on the principles of quantum mechanics to better explain the behavior of electrons in atoms.
What is a mixed state in quantum mechanics?
The mixed state in quantum mechanics is the statistical ensemble of the pure states.
What you need to study the quantum mechanics?
To study quantum mechanics, you would need a strong foundation in physics and mathematics, including topics such as calculus, linear algebra, and differential equations. Additionally, knowledge of classical mechanics and electromagnetism would be beneficial. Understanding key concepts like wave functions, probability theory, and quantum states is essential for delving into the complexities of quantum mechanics. Access to textbooks, academic journals, and online resources would also be valuable for gaining a deeper understanding of this fascinating field.
How is atomic structure determined by quantum mechanics?
Quantum mechanics describes the behavior of particles at the atomic level by providing a probabilistic framework for their position and properties. The electron's position around the nucleus is described by a probability distribution known as an orbital. Quantum numbers define the allowed energy levels and spatial distribution of electrons within an atom, ultimately determining its atomic structure.
Why plasma is not explained with quantum mechanics?
I am not aware of it "not being explained". I would guess that you can explain the relevant aspects with quantum mechanics.
Why did schrodinger use probability?
Erwin Schrödinger was a physicist and a father of quantum mechanics. Quantum mechanics deals a lot with probability. His famous Schrödinger equation, which deals with how the quantum state of a physical system changes in time, uses probability in how it deals with the local conservation of probability density.

Why is concept of trajectory meaningless in quantum mechanics?
Because there are no definite positions. There are only probability distributions.
Does quantum and wave mechanics deal with matter?
Yes, as well as other things. Quantum mechanics (also called wave mechanics) is the only approach that can accurately predict the probability of where and in what state matter will end up, given certain initial conditions.
What is the division of mechanics in physics?
the classification of mechanics are:- # Classical Mechanics # Statistical Mechanics # Quantum Mechanics
Quantum mechanics can be used to calculate the probability of an electron's what at any given time?
An electron's location or momentum, but not both.
What is necessary for you to be able to explain what happens during radioactive decay?
To fully explain radioactive decay you need quantum mechanics.
What is the density matrix?
The density matrix refers to the quantum mechanical analogue to a phase space probability measure in the classical statistical mechanics.
A region in which there is a high probability of finding an electron is called a field true or false?
False. A region in which there is a high probability of finding an electron is called an orbital in quantum mechanics, not a field.
When was Principles of Quantum Mechanics created?
Principles of Quantum Mechanics was created in 1930.
How statistics relative to other subjects?
One subject they're important in is physics. Statistics play such a big role in thermal dynamics that it is often referred to as statistical mechanics. Also, probability theory uses statistics as its base and quantum mechanics is all about probability.
