Understanding Light and Colored Solutions

The first page introduces fundamental concepts of light interaction with colored solutions. White light decomposition through a prism creates a continuous spectrum of visible radiation between 400 and 800 nm.

Definition: White light spectrum encompasses all visible wavelengths from violet to red (400-800 nm).

Vocabulary: A colored solution selectively absorbs certain wavelengths while transmitting others, resulting in the perceived color.

Example: A pure iodine solution appears green because it absorbs blue light, demonstrating the principle of complementary colors.

Highlight: The perceived color of a solution is complementary to the absorbed radiation, as shown in the chromatic circle.
