Light sucking flames look like magic

Summary by Krater

Steve Mould explains the science behind making a black flame using sodium street lamps and salt water, and demonstrates how EnChroma glasses work by analyzing their effect on the emission spectra of light sources.

Answers: How does a black flame work and what do EnChroma glasses do to the light spectrum?

• Sodium street lamps
• Atomic emission and absorption spectra
• Electron orbital transitions
• Spectroscopy and diffraction gratings
• Electron spin and magnetic moments
• EnChroma glasses
• Bunsen burner mechanism

What it concludes

• Sodium atoms absorb the exact 590 nanometre photons that are emitted by sodium street lights, causing a black flame when illuminated.
• EnChroma glasses selectively filter out wavelengths around the peak overlap of red and green cone cells to enhance color contrast for color-blind individuals.
