Studying Suggestions for Light and Color Quiz #1 

The next quiz will be on Friday, February 14. The quiz will be a one-page quiz, covering both sides of a single sheet of paper. Bring your centimeter ruler/protractor and be ready to think and diagram. Students can expect the following concepts, skills, and problem-types to be assessed on this quiz:

  1. Define interference and distinguish between constructive and destructive interference; identify the unique features of a two-point source interference pattern (nodal and antinoldal lines) and explain how these features are produced.

    || Two Point Source Interference ||


  2. Express qualitatively how variations in wavelength or source separation distance (d) effect the number of nodal and anti-nodal lines in a two-point source interference pattern.

    || Animation of Two-Point Source Interference Patterns: #1, #2 ||


  3. Relate the path difference to the wavelength and to be able to explain the relationship; solve problems involving path difference and wavelength.


  4. Explain how Thomas Young was able to measure the wavelength of visible light; discuss how the bright and dark fringes on an interference pattern are formed; use Young's equation to solve mathematical problems relating measurable quantities on a two-point source interference pattern.


  5. Distinguish between polarized and unpolarized light and explain the effect of Polaroid filters and combinations of filters on the vibrational tendencies of light.
