1. Light is a spectrum: Sunlight, or white light, is composed of all the colors of the rainbow, each with a specific wavelength.
2. Absorption: The Key Player: When light hits an object, some wavelengths are absorbed by the object's molecules, while others are reflected or transmitted.
3. The Color We See: The color we perceive is the result of the wavelengths that are *not* absorbed. These reflected or transmitted wavelengths reach our eyes, and our brains interpret them as a particular color.
Here's a simplified example:
* A red apple: The apple absorbs most wavelengths of light except for red. The red light is reflected back to our eyes, so we see the apple as red.
* A green leaf: A green leaf absorbs most colors except for green. The green light is reflected, giving the leaf its color.
Some key concepts to understand:
* Pigments: Pigments are substances that absorb certain wavelengths of light and reflect others. They are responsible for the color of many objects, such as paints, dyes, and even our skin.
* Transparent objects: Transparent objects, like glass, allow most wavelengths of light to pass through them. This is why they appear colorless.
* Opaque objects: Opaque objects absorb most wavelengths of light, reflecting very little. This is why they often appear dark or black.
Think of it like this:
* Absorption is like a filter: Each object acts like a filter, allowing certain colors to pass through and blocking others.
* The color we see is the "leftover" light: The color we see is determined by the light that wasn't absorbed.
