### Studying Suggestions for Refraction Quiz #1

2013-2014

The next quiz will be on Tuesday, 5. The quiz will be a short, one-page quiz, covering both sides of a single sheet of paper (and possibly one side of a second sheet of paper). 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.

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.

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.
