Spectra and color

Overlooked pulling a microscope to allow the scope to reach ambient temperature. Pulled the scope at 9:15, was fine for 11:30 section after the color vision videos. 

Began the 9:30 session with the CD spectrograph boxes. The above is a Pixel 7 Pro rendering of the spectrum. Still lacks the smoothness of the color gradient that the human eye perceives. Exaggerates the cyan band relative to the human eye, dimishes the violet band.

The students saw six colors which were recorded on the board. One student saw a color beyond red which they called maroon.

Then The Limits of Light video was shown.

At 11:30 I rolled the color playlist. The filters video can be removed. Jumped out of both Vsauce videos, one at the lemons can also make electricity. The second at we are all alone in our minds. Limited value to qualia in a summer term. After minus green I then showed the class the pixels on a Pixel 7 Pro. This now requires the use of the 10x lens. The 4x lens is no sufficient to tender the pixels clearly.

I forgot the yellow towel to use to show real yellow versus fake yellow. A photo of my shirt served the same functional purpose.

A demonstration was done to set up custom color in Desmos. This should have been in slow motion a second time.

Setting the opacity to one solidifies the circle should one desire to do so.

While the students worked on the RGB questions, I present the hue circle.

One problem down at HSLA: the Smartboard browser cannot show the code so I cannot show thecHDLA color angle. Perhaps a link to a text file would work.
