How do you make the difference between blackbody thermal and elemental spectrum ?
@NatSciDemos
@NatSciDemos 3 жыл бұрын
In general a blackbody will emit a continuous range of colors, while an excited element will emit only discrete colors. For example in the video, the glowing hot platinum wire will show up as a continuous spectrum, while the burning calcium will show up as discrete green, yellow, and red colors.

Sirs, verily I do regret to tell you of this and do not wish to alarm, but I think your Ba is contaminated with Na!

Indeed. Are you noticing that sodium line in almost all of the flame tests? Sodium is a wicked efficient emitter, and a common contaminant of other salts.

@@DanielRosenberg ya I was just messin around. Of course Bunsen and Kirchoff noticed the remarkable efficency of Na as an emitter of light some century and a half ago and I guess it's probably the reason every street on the planet was lit with sodium and not calcium or strontium light up until just a few years ago when LEDs took over...

Perhaps to make sure they don’t get sick from the burning of the metals?
