Study Notes
- Subtractive color mixing is more complex than additive color mixing with colored spotlights.
- In subtractive process, cyan filter transmits blue and green light, absorbs red; yellow filter transmits green and red light, absorbs blue; magenta transmits red and blue light, absorbs green and white.
- Complementary colors: Magenta (shortest wavelength), Cyan, Yellow.
- Production of colors through absorption: Objects absorb specific wavelengths based on their molecular vibrational frequencies, resulting in color separation.
- Additive color mixture: Combining blue, green, and red lights produces cyan, yellow, and magenta secondary colors, with white light at the center.

Description
Test your knowledge on light absorption and scattering phenomena. Learn about how certain frequencies of light are absorbed by objects, causing them to become warmer, as well as how the color of the sky is due to the scattering of light in the atmosphere.
