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.

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 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.
What is a mixed state in quantum mechanics?
The mixed state in quantum mechanics is the statistical ensemble of the pure states.
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.
What does the wavefunction from quantum mechanics describe?
The wavefunction in quantum mechanics describes the probability of finding a particle in a particular state or location.
What is the relationship between the probability density function and quantum mechanics?
In quantum mechanics, the probability density function describes the likelihood of finding a particle in a particular state. It is a key concept in understanding the behavior of particles at the quantum level.
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.

What is the significance of the amplitude of an electron wave in quantum mechanics?
The amplitude of an electron wave in quantum mechanics represents the probability of finding the electron at a specific location. It is a key factor in determining the behavior and properties of electrons in the quantum world.
Why is concept of trajectory meaningless in quantum mechanics?
Because there are no definite positions. There are only probability distributions.
What is the significance of the psipsi function in quantum mechanics?
The psipsi function in quantum mechanics represents the probability density of finding a particle at a specific location. It is significant because it helps determine the likelihood of where a particle may be located in a quantum system.
What is the significance of the wave function in quantum mechanics?
The wave function in quantum mechanics is significant because it describes the probability of finding a particle in a particular state. It is a fundamental concept that helps us understand the behavior of particles at the quantum level.
What is the difference between angular and radial nodes in the context of quantum mechanics?
In quantum mechanics, angular nodes are regions where the probability of finding an electron is zero along a specific axis, while radial nodes are regions where the probability of finding an electron is zero along the distance from the nucleus.
What is the significance of the radial probability distribution in quantum mechanics?
The radial probability distribution in quantum mechanics shows the likelihood of finding an electron at a certain distance from the nucleus in an atom. It helps us understand the electron's behavior and the structure of atoms, which is crucial for predicting chemical properties and reactions.
