Request for Link on orbital decay energy characteristics

In summary, the conversation discussed the relationship between the generation of lower frequency waves and light waves, specifically focusing on the quantum and wavelike nature of electromagnetic radiation produced by electron orbital decay. The participants also mentioned the hyperfine structure line of hydrogen at 1420 MHz and provided a link to an article on the topic. The conversation concluded with a mention of another link that applies to the interest in visible light photon characterization.

While reading an older article by Schrodinger on Causality a question occurred to me about the nature of energy/time characteristics of light emitted by electron orbital decay.

I have been thinking for some time on the relationship/contrasts between generation of lower frequency (ie radio) waves and light waves.

Any links to good articles/information on quantum/wavelike nature of EM radiation produced by electron orbital decay would be appreciated

The lowest frequency / longest wavelength emission line of hydrogen is the hyperfine structure line at 1420 MHz / 21 cm.
See http://en.wikipedia.org/wiki/Hydrogen_line

It is due to the coupling of the magnetic moments of the electron in the 1s atomic (ground) state and the proton.

Thanks for the link on the hydrogen microwave line. Interesting; a small energy change resulting in a microwave frequency.

I found this link previously and just realized that some of the information applies to my interest in visible light photon characterization.

1. What is orbital decay energy?

Orbital decay energy is the energy released when a satellite or other object in orbit loses altitude and eventually falls back to Earth. This energy is a result of the object's kinetic energy being converted into heat and sound upon reentry into the Earth's atmosphere.

2. How does orbital decay energy affect satellites?

Orbital decay energy can cause satellites to lose altitude and eventually fall back to Earth, rendering them unusable. It can also affect the accuracy and stability of a satellite's orbit, leading to potential collisions with other objects in orbit.

3. What factors contribute to orbital decay energy?

The main factor that contributes to orbital decay energy is atmospheric drag, which is caused by Earth's atmosphere interacting with the object in orbit. Other factors include solar radiation and the gravitational pull of the Moon and Sun.

4. Can orbital decay energy be used for renewable energy?

No, orbital decay energy is not a viable source of renewable energy. While it does release energy upon reentry into the Earth's atmosphere, the amount is relatively small and not sustainable for generating power.

5. How do scientists measure orbital decay energy characteristics?

Scientists can measure orbital decay energy characteristics through various methods such as tracking the satellite's altitude and speed, analyzing atmospheric data, and using mathematical models to predict the object's decay rate. They can also physically collect and analyze debris from reentry events to study the energy released.
