Homework Help Overview

The discussion revolves around atomic physics, specifically the behavior of an electron spiraling into the nucleus and its implications on orbital frequency, emitted radiation frequency, and the type of spectrum produced.

Discussion Character

  • Exploratory, Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • The original poster attempts to reason through the effects of an electron's spiraling motion on its orbital frequency and the emitted radiation frequency. Some participants question the consistency of the original poster's reasoning regarding the quantization of energy and its implications on the electron's ability to spiral into the nucleus.

Discussion Status

The discussion is ongoing, with participants providing clarifications and raising questions about the original poster's assumptions. There is an acknowledgment of conflicting reasoning presented in the responses, indicating a productive exploration of the topic.

Contextual Notes

Participants are discussing the implications of Maxwell's laws of electromagnetism and the quantization of energy in the context of atomic physics, with some potential misunderstandings about the relationships between frequency, energy, and emitted radiation.

Homework Statement


According to Maxwells laws of electromagnetism:
If an electron spirals into the nucleus:
1. what would happen to the electron’s orbital frequency?
2. what would happen to the frequency of the emitted radiation? and
3. what kind of spectrum would be produced—a continuous or line spectrum? Explain.

2. Homework Equations are:

Angular frequency =

(f is also written with the symbol of speed, v)

Circular motion = [PLAIN]https://upload.wikimedia.org/math/9/d/1/9d1cb34656f4ed9ce94952c445bcaa90.png[/B] 3. The attempt at a solution
I am not sure if these answers are correct but:

1. The electrons orbital frequency would increase because the orbit gets smaller and smaller as the relationship between the frequency and the radius is inversely proportional.
2. The frequency of the emitted frequency will also decrease because according to Maxwell's law of electromagnetism the orbital frequency of a electron will match up with the frequency of the emitted radiation.
3. If an electron spirals into the nucleus, a line spectrum would be produced. This is due to the fact that electron energy is quantized and it needs to release a set amount of energy in order to go down to the previous energy level.

What appears to be 'v' to you is actually lower case Greek letter 'nu' ( ##\nu## ), which is often used in atomic physics to indicate frequency.

The Planck relation ##E = h\nu## is usually written this way.
 
Thank you for you help SteamKing
 
You have a bit of a conflict between your reasoning for (a) and (c).
In (c) you say that the emitted energy is quantized, but if this is the case then
the electron reaches a point where it cannot fall into the nucleus because
it cannot obtain the energy to emit the photon.
Also, if the electron is "spiraling" what does that imply about the emitted radiation?
