SUMMARY

The discussion focuses on calculating energy from wavelengths using the equation ΔE = hv, where h represents Planck's constant and v is the frequency of the light. Participants clarify that R refers to the Rydberg constant, which is essential for determining energy levels in atomic transitions, while c denotes the speed of light. The confusion arises from the correlation coefficient R² mentioned in the plot, which is distinct from the Rydberg constant. This highlights the importance of understanding both the physical constants and the context of the plotted data.

PREREQUISITES
  • Understanding of the equation ΔE = hv
  • Familiarity with the Rydberg constant
  • Knowledge of the speed of light (c)
  • Basic skills in plotting and interpreting data
NEXT STEPS
  • Research the significance of the Rydberg constant in atomic physics
  • Learn how to calculate frequency from wavelength
  • Explore the relationship between energy, frequency, and wavelength
  • Study correlation coefficients and their interpretation in data analysis
USEFUL FOR

Students in physics or chemistry courses, educators teaching energy calculations, and anyone interested in the principles of quantum mechanics and atomic structure.

Homework Equations





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.
