Chapter 8: Problem 94

In everyday usage, the term "quantum jump" describes a change of a very significant magnitude compared to more gradual, incremental changes; it is similar in meaning to the term "a sea change." Does quantum jump have the same meaning when applied to events at the atomic or molecular level? Explain.

Short Answer

Expert verified
No, 'quantum jump' does not have the same meaning when applied to events at the atomic or molecular level as it does in everyday usage. In quantum physics, it refers to a sudden, discontinuous change when an electron transitions from one energy level to another within an atom. In everyday language, it is used to symbolize significant and dramatic changes that are not necessarily abrupt or discontinuous.

Step by step solution

01

Defining Quantum Jump in Everyday Usage

In common parlance, a 'quantum jump' or a 'sea change' refers to a significant, sudden, and often pronounced change. However, it must be clarified that in the realm of physics, and particularly quantum physics, this term has a specific meaning.
02

Explaining Quantum Jump in Quantum Physics

In quantum physics, a 'quantum jump' refers to the transition of an electron within an atom from one energy level to another. This is a discontinuous change, unlike the gradual changes often implied in everyday language. When an electron makes such a jump, it either absorbs or emits energy in the form of a photon, resulting in the bright line spectra observed in quantum experiments.
03

Comparing the Two Usages

Therefore, while the everyday and atomic level usage of the term 'quantum jump' both signify some form of change, the nature of that change is different. In everyday use, it is a metaphor symbolizing a significant shift, while in physics, it is a specific, discontinuous, and observable transition of an electron between energy levels in an atom.

A molecule of chlorine can be dissociated into atoms by absorbing a photon of sufficiently high energy. Any excess energy is translated into kinetic energy as the atoms recoil from one another. If a molecule of chlorine at rest absorbs a photon of 300 nm wavelength, what will be the velocity of the two recoiling atoms? Assume that the excess energy is equally divided between the two atoms. The bond energy of \(\mathrm{Cl}_{2}\) is \(242.6 \mathrm{kJ} \mathrm{mol}^{-1}\)
