  1. Write out the full names of the seven colors of the Newtonian rainbow IN ORDER:
  2. What is the scientific name for the spread of colors that was seen in the box with the CD?
  3. List the three primary colors of light:
  4. List the three secondary colors of light:
  5. Hue Saturation Luminosity (HSL) colors:
  6. ________________ What color of light does an orange pumpkin reflect?
  7. ________________ What color of light does an orange pumpkin absorb?
  8. As noted in class, indigo was added to the rainbow by Newton to generate a seven color rainbow. Looking at a spectrum, however, there really is no visually different color at the position of indigo. If indigo were to be replaced, what color would you add to the other six rainbow colors, the spectrum, and why?
  9. Describe in your own words retinex theory.
  10. ______________ ______________ _____________ What does the acronym LCD stand for?
  11. What is an AMOLED display and what are the advantages to an AMOLED display?
  12. What is a Quantum Dot LCD display and what advantages does the quantum dot display have?
  13. Define reflection.
  14. Define refraction.
  15. Define total internal reflection.
  16. ______________ Based on the data below, what is the index of refraction for water?

    1. ______________ Calculate the slope of the line. The slope is the experimental index of refraction for water.
    2. ______________ __________ Use the slope above to predict the object depth for a penny that appears to be 30 cm underwater.
    3. ______________ __________ Use the slope above to predict the image depth for a coral head that is 200 cm underwater.
    4. ______________ Water has a published index of refraction of 1.33. What is the error for the slope?
    5. ______________ Water has a published index of refraction of 1.33. What is the percentage error for the slope?

error = experimental value − expected or published value

percent error= (experimental value−expected value) (expected value)

slope= ( y2 − y1 ) ( x2 − x1 )
