Absorption of Radiation01:05

Absorption of Radiation

1.6K
The rate of heat transfer by emitted radiation is described by the Stefan-Boltzmann law of radiation:

Radiation: Applications

2.0K
The average temperature of Earth is the subject of much current discussion. Earth is in radiative contact with both the Sun and dark space; it receives almost all its energy from the radiation of the Sun and reflects some of it into outer space. Dark space is very cold, about 3 K, so Earth radiates energy into it. For instance, heat transfer occurs from soil and grasses, the rate of which can be so rapid that frost can occur on clear summer evenings, even in warm latitudes.
The average...

Hyperbolas01:30

Hyperbolas

547
A hyperbola is a conic section produced when a double-napped cone is intersected by a plane at an angle steeper than the slope of the cone, such that it cuts through both nappes. This intersection yields two separate, mirror-image curves known as branches, which open away from each other along the transverse axis. The nearest points on each branch to the hyperbola’s center are termed vertices, and the distance from the center to a vertex is denoted by a. Perpendicular to the transverse...

Thermal Sigmatropic Reactions: Overview

2.7K
Sigmatropic rearrangements are a class of pericyclic reactions in which a σ bond migrates from one part of a π system to another. These are intramolecular rearrangements where the total number of σ and π bonds remain unchanged.
Sigmatropic shifts are classified based on an order term [i, j ], where i and j indicate the number of atoms across which each end of the σ bond migrates. Below are examples of a [3,3] sigmatropic shift in 1,5-hexadiene, referred...

Maxwell's Thermodynamic Relations01:23

Maxwell's Thermodynamic Relations

4.9K
Maxwell's thermodynamic relations are very useful in solving problems in thermodynamics. Each of Maxwell's relations relates a partial differential between quantities that can be hard to measure experimentally to a partial differential between quantities that can be easily measured. These relations are a set of equations derivable from the symmetry of the second derivatives and the thermodynamic potentials.
All thermodynamic potentials are exact differentials. Therefore, their second-order...

Emission Spectra02:39

Emission Spectra

78.7K
When solids, liquids, or condensed gases are heated sufficiently, they radiate some of the excess energy as light. Photons produced in this manner have a range of energies, and thereby produce a continuous spectrum in which an unbroken series of wavelengths is present.

Area of Science:

  • Thermodynamics
  • Electromagnetism
  • Materials Science

Background:

  • The standard blackbody theory, based on Planck's law, describes thermal electromagnetic fields in isotropic media.
  • Uniaxial anisotropic media exhibit distinct optical properties compared to isotropic materials.
  • Understanding thermal radiation in anisotropic media is crucial for various applications.

  • To re-examine blackbody theory within hyperbolic uniaxial anisotropic media.
  • To investigate deviations from Planck's predictions for spectral energy density.
  • To derive modified laws for thermal radiation in these specific media.

Main Methods:

  • Theoretical analysis of thermal electromagnetic fields.
  • Application of concepts from statistical mechanics and electromagnetism.
  • Derivation of spectral energy density and radiation laws.

Main Results:

  • Spectral energy density in hyperbolic anisotropic media significantly differs from Planck's blackbody theory.
  • Wien's displacement law shows a redshift in the spectral energy density maximum.
  • The Stefan-Boltzmann law is modified, becoming a quadratic function of temperature.

Conclusions:

  • The behavior of thermal radiation in hyperbolic anisotropic media deviates substantially from standard blackbody predictions.
  • Modified Wien's and Stefan-Boltzmann laws are established for these media.
  • These findings have implications for understanding thermal phenomena in anisotropic materials.
