Let's get a better mental model beyond just "because blue light scatters more". I stream science LIVE M-W-F 1pm PT.
Here is Sally's channel!! She is live streaming a series on evolutionary biology- alnets.info
BOSE will be sending out 8 pairs of their dope 700 headphones. 4 will go to people who post about our class on Insta, Twitter, FB or TikTok. 4 will go to my favorite challenge responses or answers to questions. You can post your challenges by tagging me on any social media platform.

At sunsets, does the frequency of blue changes to lower frequency so it looks warmer? Or only the lower frequencies can travel through all the atmosphere?

As a physics teacher, I love these videos and would love to use them in my classes, but the auto-captions that they currently have do not meet ADA standards for my Deaf and Hard of Hearing students. ALnets makes it pretty easy to go through and edit the captions for grammar and accuracy (ie adding punctuation and correcting any words that did not transcribe properly). I know some of your videos have full and proper captions, would love to see that for this video as well!

My teacher always said that scattering is inversely proportional to wavelength and so violet or blue scatters the most but never explained why, but now i understand totally why the sky is blue and that it had something to do with resonance which i never knew! Thank you very much! Much love from India and Happy Engineer's Day!

the reason the sky is blue is because we live on a plane covered by an impenetrable dome and the dome material has a blueish hue. now you've actually learned something

I'm so lost, please someone explain. I've haven taught that the sky is white color and we see it as blue because of the ocean reflection, (in my science class). In this video I learn that it's blue because of the frequency that the sun sent. Thank you in advance.
