  1. partial hydrogen spectrum produced by CD spectroscope partial hydrogen spectrum produced by CD spectroscope
    ______________ The hydrogen gas spectrum is seen in the image on the left. Is this a continuous or discrete sprectrum?
  2. ______________ The lines from left to right are red, cyan, and purple. Which of these three has the longest wavelength (which is the same as saying "the lowest frequency")?
  3. ___________________ What is the box-like object in the picture with the candle called?
    pinhole camera
  4. _____ A laser is beamed into a semi-circular dish of water. Will the light come out at A or B?

    1. ______________ Calculate the slope of the linear best fit line. The slope is the experimental index of refraction for the material.
    2. ______________ The above material is reported to have a theoretic index of refraction of 1.33. What is the percentage error for the slope you calculated based against a theoretic value of 1.33?
