This is a demonstration of the continuous spectrum of white light and the emission spectra of mercury, nitrogen, neon, and hydrogen, imaged through a diffraction grating.
This demonstration was created at Utah State University by Professor Boyd F. Edwards, assisted by James Coburn (demonstration specialist), David Evans (videography), and Rebecca Whitney (closed captions), with support from Jan Sojka, Physics Department Head, and Robert Wagner, Executive Vice Provost and Dean of Academic and Instructional Services.

It's one thing to see this in textbook diagrams, but to see it happen in reality with an actual professor explaining it is mind blowing!

sir, you showed a fantastic experiment - which is generally not available even in university laboratories. Thanks for sharing it to world.

“To prevent burning flesh” I can see why they don’t do this experiment in many schools

@Holdenreecespieces 3 года назад

@@jalynnecardany4865 it's about the same level of danger as cooking on the stove, as long as you know the risks and aren't being careless. Don't touch the pan of boiling water with your hand directly, lmao. And also don't touch the electric source.

Wish Indian schools should have demonstrated to students in this way so that everybody could understand.

@easytogowithphysics 4 года назад

We are working on it,but it will take time, but the thing is we are living in an environment where it doesn't matter how things came, how derivation came, how does particular thing look but we see how much we score in, jee, boards, neet etc. This should be changed

amazing. I´ve studied chemistry and even with master degree studying spectroscopy in 90´s that´s the first time I see how this works experimentally.

Thank you for the demonstration. It might have been helpful if you could explain what the colors would represent to those who are new to understanding what properties they contain.

@boydedwards5475 6 лет назад

You're right, Rita. There's a lot more context needed than just the demonstration. Those interested in more information might be encouraged to view my lecture segments 30.1, 30.2, 30.3, and 30.4

@physicsdemos 5 лет назад

Great suggestion, Rio. In fact, I have done just that. See my lecture on the nature of the atom: ru-vid.com/group/PLkRMGCE8BEtakj1jBWNgIJcdwprADiOzC.
