10/16 Lecture Demo on Atomic Spectra

Postby Emily Jacobo 1C » Sun Oct 18, 2020 12:52 pm

Hi! So during the lecture's demo on friday, Professor Lavelle told us about the different gases in each section, but I didn't catch the name of the gas used in the bottom section (with the white and rainbow light). Does anyone know the gas? Just want to make a note of these gases and what they look like.

Hi Emily!
I believe it was white light / visible light.
from top to bottom: helium, neon, mercury, white light.

I was a bit confused about this too, but I believe there's no gas inside. Professor Lavelle mentioned just a traditional visible bulb.

Oh my bad. I didn't actually answer your question directly, but yeah I don't think there was any gas in the bottom. I think it was displayed so we could compare it to how gases emit specific and different wavelengths of light.

Oh okay that makes sense! I just thought as there were gases in the other sections, but it makes sense now. Thank you!

I understood what you meant. Thank you though! Yeah it seems there was no gas in the bottom, just a light bulb.
