Behaviour of hydrogen in an electric field

Click For Summary

Discussion Overview

The discussion centers on the behavior of hydrogen atoms in an electric field, specifically regarding the Stark effect experiment. Participants explore practical considerations for generating a high electric field and connecting a hydrogen tube to it.

Discussion Character

  • Exploratory, Technical explanation, Experimental/applied

Main Points Raised

  • One participant, Amal Mirando, seeks guidance on producing a 100,000 v/cm electric field and connecting a hydrogen tube for the Stark effect experiment.
  • Another participant suggests consulting general physics books for methods to create an electric field using specific charge.
  • A later reply mentions finding an induction coil capable of generating the required electric field.
  • It is proposed that the electric fields can be applied through the walls of the hydrogen tube, with the configuration of plates affecting the voltage needed.
  • Concerns are raised about the high field strength potentially ionizing the hydrogen, leading to plasma formation, and a question is posed regarding the origin of the specified field strength.
  • Amal clarifies that the field strength is based on historical values provided by Stark in 1914, with the intention to observe spectral line splitting.

Areas of Agreement / Disagreement

Participants express varying levels of agreement on the feasibility of generating the electric field and the implications of the field strength, but no consensus is reached on the best approach to the experiment.

Contextual Notes

Participants do not fully resolve the technical details of the experiment, including the assumptions about the electric field's effects on hydrogen and the specific setup required.

behaviour of hydrogen in an electric field...

hi,
i'm conducting a research in studying the behaviour of hydrogen atom in an electric field and hoping to carryout the stark effect expeiment.i found a hydrogen tube in the lab but the following issues have risen...

(1) how do i produce around 100,000 v/cm electric field?
(2) how to connect the hydroen tube to this field? (whether to apply above field to both ends or place the tube in between the field)

i browsed through the internet and found absolutely nothing about carrying out this experiment.so if there are people who've carried out the experiment can help me with this?

anybody got ideas?....
 


Read any General physics book and you will find how to make ana electric field with the specific charge and so on. The rest of the experiment you have to use your mind
 


hey,thanks for the idea...i have found an induction coil which is capable of producing the required field...
 


The fields can be applied right through the walls of your tube. Assuming the tube is longer than it is wide, plates above and below will have closer spacing and thus reduce the voltage you need to generate. The field strength you mention sounds awful high--you will probably tear the electrons off their nuclear to produce a plasma. Where did you get that value?
 


thanks for the idea...the above mentioned field is what Stark provided in 1914 to verify stark effect..my idea is to witness the splitting of spectral lines ...
