Spectra (HSC SSCE Physics): Flashcards

Pattern of light separated into component wavelengths

Bright coloured lines on dark background

Dark lines on continuous coloured background

Unique (acts as fingerprint)

UV region, $n_f = 1$

Visible region, $n_f = 2$

Infrared region, $n_f = 3$

Shorter wavelength (more energy)

At precisely the same wavelengths

Electron transitions between energy levels
