SUMMARY

The discussion focuses on solving for n(initial) in Rydberg's formula, specifically the equation 1/6.653*10^5 = 1.1*10^5 cm-1 (1/22 - 1/n2). Participants emphasize the importance of unit placement, clarifying that the 105 should be in the numerator. The conversation highlights the straightforward nature of extracting n2 from the equation, indicating that the solution process is not overly complex.

PREREQUISITES
  • Understanding of Rydberg's formula
  • Knowledge of algebraic manipulation
  • Familiarity with unit conversions in physics
  • Basic concepts of quantum mechanics

Are your sure you're using the right units...?Is that 10^5 in the LHS in the numerator or in the denominator...?It better be "upstairs".

I'm sure it's not 2 difficult to "extract" n^2 from that equation.

Thread 'Gold hydride - what is the significance?'

I came.across a headline and read some of the article, so I was curious. Scientists discover that gold is a 'reactive metal' by accidentally creating a new material in the lab https://www.earth.com/news/discovery-that-gold-is-reactive-metal-by-creating-gold-hydride-in-lab-experiment/ From SLAC - A SLAC team unexpectedly formed gold hydride in an experiment that could pave the way for studying materials under extreme conditions like those found inside certain planets and stars undergoing...
