Calculate the energy of a photon emitted when an electron in a hydrogen atom undergoes a transition from =6 to =1.
scoundrel [369]

When an electron in a hydrogen atom transitions from the state of n=6 to n=1, a photon with an energy of 13.2 eV is released.

<h3>What components make up a photon?</h3>
  • A photon is a microscopic particle that is part of electromagnetic radiation waves.
  • Maxwell demonstrated that photons are merely electric fields flowing through space.
  • A single photon can trigger a response from sensors in the retina.
<h3>What is the difference between an electron and a photon?</h3>
  • Photons and electrons. One of the fundamental quantum-mechanical particles is an electron, although photons also exist and have entirely distinct properties.
  • While the electron is a subatomic particle found in every atom, the photon is a sort of elementary particle that serves as an energy carrier.

Explain why Planck’s introduction of quantization accounted for the properties of black-body radiation.
DochEvi [55]

Explanation:

The classic model of a black body made predictions of the emission at small wavelengths in open contradiction with what was observed experimentally, this led Planck to develop a heuristic model. This assumption allowed Planck to develop a formula for the entire spectrum of radiation emitted by a black body, which matched the data.

Semiconductors can simplistically be thought of as an intermediate state between insulators and conductors. In a semiconductor,
Triss [41]

Answer:

The semiconductor rod will conduct electricity

Explanation:

Glass rod does not conduct electricity. Glass is one of the best insulators of electricity. But when a glass rod is replace with a semi conductor, then the semi conductor rod starts conducting electricity as the electrons are free to move.

Semi conductors are special materials in which the energy band lies in between the conductor and the non conductor. The conductivity of a semi conductor increases with the increasing temperature.

In an semi conductor the electrons are free to move and as they starts moving they conduct electricity. Thus a semi conductor rod replacing a glass rod conducts electricity.
