Presentation Transcript

  1. Chapter 17Reflection and Refraction

  2. Ch 17.2 Applications of Reflected and Refracted Light

  3. I. Applications of Reflected and Refracted Light A. Total internal reflection B. Effects of refraction C. Dispersion of Light

  4. Θr Θi Θr Θi A. Total internal reflection • Critical angle

  5. Calculating the critical angle • ni sin Θi = nr sin Θr • Θi = Θc • sin Θc = nr / ni • Note: you can only have total internal reflection when going from a more dense to a less dense medium. (ex. water to air) • Applications of total internal reflection.

  6. B. Effects of Refraction • Positions of objects in liquids • Mirage effect • Extended daylight

  7. C. Dispersion of Light • The separation of light into its spectrum • Other materials that disperse light • Diamond • Spectra of different light sources • Formation of rainbows

  8. Homework • Chapter 17 review problems 50 - 58
