Discussion Overview

The discussion revolves around calculating energy from wavelengths using the equation deltaE = hv. Participants are addressing a homework problem related to this concept, including how to interpret a plot and identify relevant constants.

Discussion Character

  • Homework-related, Technical explanation

Main Points Raised

  • One participant expresses uncertainty about how to find energy using the equation deltaE = hv after calculating wavelengths and plotting values.
  • Another participant suggests that the problem seems straightforward, implying it should be a matter of substituting values into the equation.
  • A different participant seeks clarification on the meanings of R and c in the context of the problem.
  • A later reply clarifies that R refers to the Rydberg constant, which is to be derived from the plot, while c represents the speed of light. It also notes that R2 mentioned in the plot likely refers to a correlation coefficient, which could lead to confusion.

Areas of Agreement / Disagreement

Participants do not appear to reach a consensus on the specific challenges faced in solving the problem, as some express confusion while others see it as straightforward.

Contextual Notes

There may be limitations in understanding the plot and the definitions of the constants involved, which could affect the clarity of the discussion.

The Attempt at a Solution


I calculated all the wavelengths, and plotted the values, but how do I find energy from the equation deltaE = hv?
Thanks in advance!

Looks to me like just a plug and chug, I am not sure what's the problem.

But what is the R, and what is the c?

thanks.
 
R is what you are to find from the plot (so called Rydberg constant), c is the speed of light.

R2 mentioned on the plot seems to be a correlation coefficient, this can be confusing.
