Visible rays under Magnetic field of the earth

Click For Summary

Discussion Overview

The discussion revolves around the hypothetical scenario of visible radiation from the sun being charged and its implications under Earth's magnetic field. Participants explore the effects of charged particles, cosmic rays, and the behavior of these particles in relation to Earth's magnetic field, touching on concepts of energy requirements for reaching different geographic locations.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant proposes a thought experiment about the consequences of visible radiation being positively charged and questions the potential impact on its ability to reach the ground.
  • Another participant asserts that photons cannot be charged, emphasizing the need for a physical model to discuss charged photons meaningfully.
  • A participant mentions that charged particles are deflected by Earth's magnetic field, suggesting that only high-energy particles can reach the surface, particularly near the poles where aurorae occur.
  • There is a discussion about cosmic rays, with a participant noting that 89% of cosmic radiation consists of protons.
  • One participant claims that lower energy particles require more kinetic energy to reach the poles than the equator, prompting a challenge from another participant who argues that the opposite is true.
  • A participant expresses confusion based on a book that states cosmic rays require less kinetic energy to reach the poles than the equator, indicating a discrepancy in understanding.

Areas of Agreement / Disagreement

Participants do not reach consensus on the energy requirements for cosmic rays to reach the poles versus the equator, with conflicting views presented and confusion acknowledged based on differing sources.

Contextual Notes

Participants reference assumptions about the behavior of charged particles and the influence of Earth's magnetic field, but these assumptions are not universally accepted or clarified, leading to unresolved questions about the underlying physics.

Good afternoon friends,
I was wondering, "if the visible radiations coming from sun get charged say positively charged, then what will happen?"
I am sure that most of its part will not reach the ground but some.
But can we obtain the location of black zones for the radiation?
Is it possible to say that the radiation will never reach the pole or the equator ?
Thank you in advance

You can't charge photons, they are neutral particles.
 
Yes I know that.
But I am only asking about the assumption.

It is pointless to discuss charged photons, unless you present a physical model where those particles exist (do not forget to publish it first).
However, the Earth could not exist in its current shape if photons would be charged.

Charged, massive particles get deflected by the magnetic field of the earth, and do not reach the surface unless they have a very high energy. Near the poles, some particles can reach the upper atmosphere and produce aurorae.
 
Ok If I talk about the cosmic rays. There is 89% protons exist in cosmic radiation.
 
High-energetic cosmic radiation does not care about the magnetic field of the Earth - sure it is influenced by this, but the effect is negligible if the energy is high enough.

For low-energetic particles, see above.
 
If I say the lower energy particles enter the Earth's magnetic field and now they require more kinetic energy to reach at the poles then equator then how much this statement is true?
 
It is wrong, and in fact the opposite effect is true. This is the reason why aurorae happen close to the poles. There, particles can move along the magnetic fields and reach the atmosphere. Close to the equator, they hit the field perpendicular and get deflected.
 
But somewhere I were reading some book that it'll require more K.E. to reach at the equator then poles. That's why I am pretty confuse in that.

This is in agreement with my previous posts, and different from your other posts.
Where does the confusion come from?

Well, the confusion come from a book, where I read if the cosmic rays enters the Earth magnetic field then they will require less K.E. to reach at the poles then the equator.
