What wavelenght is expected for light composed of photons

Click For Summary

Discussion Overview

The discussion revolves around determining the wavelength of light emitted during an electron transition from n=3 to n=1 in a hydrogen atom. Participants seek clarification on the calculation process and the relevant formulas involved.

Discussion Character

  • Homework-related

Main Points Raised

  • One participant asks for help in calculating the wavelength of light from a specific electron transition in hydrogen.
  • Another participant suggests using the formula E=hc/λ to find the wavelength, indicating that a formula for energy transitions should be available in textbooks.
  • A participant reports a calculated wavelength of 8.1*10^-6 m and seeks confirmation of its correctness.
  • Another participant provides a link to a resource that discusses electron transitions, suggesting it may contain useful information for the calculation.

Areas of Agreement / Disagreement

The discussion does not reach a consensus on the correctness of the calculated wavelength, and participants express varying levels of understanding and need for assistance.

Contextual Notes

There may be limitations related to the assumptions made in the calculations, such as the accuracy of the formula used or the specific context of the transition being analyzed.

What wavelength is expected for light composed of photons produced by an n= 3 to n=1 transition in a hydrogen atom?

How do u work this out? Iam pretty confused.

please help!
 
You should be able to find a formula for the energy of such transitions in your text, from the energy use E=hc/lamda to find the wavelength.
 
ok i did it and i got 8.1*10^-6 m.
Is that right? Thanxs.
