1. Who wrote Opticks?Sir Isaac Newton
2. What is Opticks known for?Demonstration that white light is composed of a spectrum of colors
3. What is the original publication date?1704
4. What is the key phenomena studied?Refraction, reflection, diffraction, interference, dispersion
5. What did Newton discover about white light in his book Opticks?He found that white light is made of many colors that can be separated by a prism and then recombined to become white again.
6. How did Newton use a prism to learn about light?He passed sunlight through a prism, which split it into a rainbow of colors, showing that light can bend and separate.

Opticks: Isaac Newton's seminal 1704 book detailing his extensive experimental investigations into the nature of light and color.
Dispersion: The phenomenon where light is separated into its constituent spectral colors when passing through a medium like a prism.
Diffraction: The bending and spreading of light waves as they pass around obstacles or through narrow openings.
Interference: The phenomenon where light waves combine, either reinforcing (constructive) or canceling out (destructive), leading to patterns of light and dark.
