  1. __________ For the data presented above, determine the index of refraction for the material by calculating the slope.
  2. __________ The above material is reported to have a theoretic index of refraction of 1.7. What is the percentage error for the slope you calculated based against a theoretic value of 1.7?
  3. ______________ How good is the agreement between the experimental and theoretic value for the data above?
  4. __________ Does the data above provide support for a theoretic index of refraction of 1.7?
  5. _____________________________ What process produces the typical rain on Pohnpei?
  6. _____________________________ What process produces rain, lightning, and thunder?
  7. _____________________________ What process produces rain as a result of wind rising up the windward slope of mountains?
  8. __________________ A tuning fork vibrates at 256 Hertz. If the speed of sound is 350 m/s, calculate the wavelength λ for the sound wave.
  9. A RipStik was ridden across a wet cloth towel soaked in water with blue food color. The RipStik was then swizzled across a large sheet of presentation paper. The RipStik traveled a distance d of 83 centimeters in a straight line in a time t of 1.3 seconds. The swizzle wave mark made by the wheel had a wavelength λ of 23.5 centimeters. The oscillation rate for the RipStik wheel was measured as 3.5 cycles in 1.3 seconds. The amplitude A of the swizzle mark was 3.25 centimeters.

    _______________ Calculate the linear velocity v for the RipStik.
  10. _______________ Calculate the frequency f for the RipStik wheel.
  11. _______________ Calculate the period τ in seconds for one oscillation of the RipStik wheel.
  12. _______________ Calculate the velocity of the swizzle wave based on the wavelength and frequency.
  13. _______________ What color is #000 ?
  14. _______________ What color is hsl(0,100%,50%)?
  15. List the seven colors of the Newtonian rainbow from lowest frequency to highest frequency.
  16. Is the spectrum shown discrete or continuous?
    discrete spectra
  17. Is the spectrum shown produced by the sun or a gas discharge tube?
    discrete spectra
  18. What are the primary colors of light?
  19. What are the secondary colors of light?
