Transition A produces light with a wavelength of 400 nm

Click For Summary

Discussion Overview

The discussion revolves around a problem involving the relationship between energy and wavelength of light produced by two transitions, specifically Transition A with a wavelength of 400 nm and Transition B with twice the energy of A. Participants are exploring how to determine the wavelength of light produced by Transition B based on this information.

Discussion Character

  • Homework-related
  • Mathematical reasoning
  • Conceptual clarification

Main Points Raised

  • One participant expresses difficulty in solving the problem and seeks assistance.
  • Another participant emphasizes a desire to learn how to approach the problem rather than just receiving the answer.
  • A participant asks for the equation that relates energy and wavelength of a photon and inquires how changing energy affects wavelength.
  • One participant suggests that doubling the frequency would double the energy, which would imply halving the wavelength.
  • A participant acknowledges the help received and reflects on their learning experience, noting a long gap since their last algebra course.

Areas of Agreement / Disagreement

Participants generally agree on the need for clarification on the relationship between energy and wavelength, but there is no consensus on the specific solution to the problem or the implications of the relationships discussed.

Contextual Notes

Some participants express uncertainty regarding the mathematical steps involved and the application of the relevant equations, indicating a need for further clarification on definitions and concepts.

Who May Find This Useful

Individuals interested in understanding the relationship between energy and wavelength in the context of light transitions, particularly those studying or revisiting concepts in physics and mathematics.

I am having difficulty with this problem. I have solved all of the other ones and got them correct, but this one is stumpimg me.

Transition A produces light with a wavelength of 400 nm. Transition B involves twice as much energy as A. What wavelenth light does it produce?

Help please.

I am not looking for the answer from anyone. I just need to know how to figure it out. I want to learn and need some assistance.
 


What is the equation relating energy and wavelength of a photon and how would changing the energy change the wavelength?

Answer in the spoiler. 1st Spoiler just has the equation, 2nd has a solution.
Eλ=hc
So for λ=400 nm E=Eo
2Eoλ=hc

So to get the same value for hc, λ must be half of the original value, so:
λ=200 nm.
 


Thanks so much for the help. I am having learning this, but it has been 20years since I have taken college algebra and there is much more going on here than algebra. Love the knowledge!
 


I'm assuming that when you double the frequency you double the energy? Which would equal halving the wavelength?
 


Ah I am late,your query has been answered already.
