Energy, Frequency, Wavelength, and the Hydrogen Spectrum (HSC SSCE Physics): Flashcards

Patterns from electron transitions between energy levels

$n_f = 1$, ultraviolet

$n_f = 2$, visible

$n_f = 3$, infrared

Lowest energy level ($n = 1$ for H)

Removing an electron from an atom completely

$E = hf$

$6.626 \times 10^{-34}$ J·s

$\frac{1}{\lambda} = R\left(\frac{1}{n_f^2} - \frac{1}{n_i^2}\right)$
