  1. Lesson 3 Splash visible light prism diffraction grating electromagnetic spectrum primary color secondary color pigment

  2. Why do we see colors? Lesson 3 a Visible light contains a mixture of wavelengths that the human eye can detect. The compact disc acts like a diffraction grating, separating white light into a spectrum of colors.

  3. How many kinds of light are there? Lesson 3 b visible light microwaves infrared waves ultraviolet rays radio waves x-rays gamma rays

  4. How do colors mix? cyan blue magenta yellow red green Lesson 3 c RGB Color Model (primary colors) CMY Color Model (primary pigments)

  5. Main Idea Lesson 3 Main idea Review What determines an object's color? An object's color is determined by the wavelengths of visible light that it absorbs and the wave lengths of visible light that it reflects.

  6. Vocabulary Lesson 3 Vocab a Review A ________________ is made of glass, plastic, or metal; contains many thin slits, and allows light rays to pass through the slits separating the white light into color. Light that the human eye can detect is ________________. An _______________ contains the full range of wavelengths. A ________________ is a triangular piece of glass or plastic that bends light. An _______________________ contains the full range of wavelengths. visible light prism diffraction grating electromagnetic spectrum

  7. Vocabulary Lesson 3 Vocab b Review ________________ are tiny solid particles that provide color. Colors not produced through the mixing process are ________________. ________________ are produced by blending primary colors. Pigments Secondary colors secondary colors pigments primary colors

  8. Infer Lesson 3 GO Review If you were provided with cyan, magenta, and yellow pigments, how could you make green? Model shows cyan and yellow combining to form green. Mixing cyan and yellow will produce green. Color model is CMY End of Lesson
