## What does discrete energy levels mean?

The discrete energy levels of an atom means the different energies by different electron paths. A hydrogen atom for instance has the energy 13.6eV for the electron path n = 1.

**What is a discrete amount of energy called?**

Energy state, also called Energy Level, in physics, any discrete value from a set of values of total energy for a subatomic particle confined by a force to a limited space or for a system of such particles, such as an atom or a nucleus.

### What is called quantum?

In physics, a quantum (plural quanta) is the minimum amount of any physical entity (physical property) involved in an interaction. Quantization of energy and its influence on how energy and matter interact (quantum electrodynamics) is part of the fundamental framework for understanding and describing nature.

**What can only exist in discrete quanta?**

Planck postulated that energy can only be emitted or absorbed in discrete amounts, which he called quanta (the Latin word for “how much”). With Planck’s hypothesis, however, the radiation can occur only in quantum amounts of energy.

## What is the difference between discrete and continuous energy?

The key difference between continuous and discrete spectrum is that a continuous spectrum does not have any discrete lines, whereas a discrete spectrum contains only the discrete lines. Therefore, a continuous spectrum is a continuous series while a discrete spectrum has separate lines or values.

**What is the difference between continuous and quantized energy?**

If the energy levels are continuous (within a given interval of energies), then a particle (or system) can in principle have any energy in that interval. If they are quantized into say E1,E2…, then a particle (or system) can have only one of those energies, and not anything in between them.

### What is quantized energy?

Energy is quantized in some systems, meaning that the system can have only certain energies and not a continuum of energies, unlike the classical case. This would be like having only certain speeds at which a car can travel because its kinetic energy can have only certain values.

**Who is the father of quantum mechanics?**

Max Planck

Niels Bohr and Max Planck, two of the founding fathers of Quantum Theory, each received a Nobel Prize in Physics for their work on quanta. Einstein is considered the third founder of Quantum Theory because he described light as quanta in his theory of the Photoelectric Effect, for which he won the 1921 Nobel Prize.

## How many dimensions are there?

The world as we know it has three dimensions of space—length, width and depth—and one dimension of time. But there’s the mind-bending possibility that many more dimensions exist out there. According to string theory, one of the leading physics model of the last half century, the universe operates with 10 dimensions.

**What is a single unit of quanta called?**

In physics, a quantum (plural quanta) is the minimum amount of any physical entity (physical property) involved in an interaction. For example, a photon is a single quantum of light (or of any other form of electromagnetic radiation).

### Is Heisenberg Uncertainty Principle?

uncertainty principle, also called Heisenberg uncertainty principle or indeterminacy principle, statement, articulated (1927) by the German physicist Werner Heisenberg, that the position and the velocity of an object cannot both be measured exactly, at the same time, even in theory.

**How do you know if a light is continuous or discrete?**

Typically one can observe two distinctive classes of spectra: continous and discrete. For a continuous spectrum, the light is composed of a wide, continuous range of colors (energies). With discrete spectra, one sees only bright or dark lines at very distinct and sharply-defined colors (energies).

## Which is the best definition of a discrete variable?

In mathematics, discrete has several specialized senses, such as “defined only for an isolated set of points,” such as a discrete (noncontinuous) variable. The mathematical discrete can be understood as “finite” or “countable.”

**What do you mean by the word discrete?**

I think when we say “discrete” it means “countable” or “enumerable”. In zoo example, although the exact mass would vary from almost 0 to say 5000kg (if that 5T elephant is indeed the biggest animal found in the zoo), we can count every individual animal at any moment.

### What’s the difference between discrete and countable math?

The mathematical discrete can be understood as “finite” or “countable.” According to Google Ngrams data, discrete has seen a dramatic rise since the 1940s. This may be due to the use of discrete in mathematical and scientific literature.

**What’s the difference between discrete and continuous numbers?**

The definition I can find is that discrete data is countable and that continuous is uncountable. Examples are given stating that integers are discrete, and real numbers are continuous. Rationals it states are controversial.
