  1. Chapter 37 Wave Optics EXAMPLES

  2. Chapter 37: Interference of Light Waves: Examples

  3. Example 37.1 Wavelength of a Light Source • A viewing screen is separated from a double-slit source by 1.2 between slits is 0.030 mm. The second order bright fringe (m = 2) is 4.5 cm from the center line. • Determine the wavelength of the light. • Calculate the distance between adjacent bright fringes

  4. Example 37.2 Fringes of Two Wavelengths • A light source emits visible light of two wavelengths:  = 430 nm and ’ = 510 nm. The source is used in a double-slit interference experiment in which L = 1.50 m and d = 0.025 mm. Find the separation between the third-order bright fringes.

  5. Example 37.3 Six slits (Quiz 37.2) • Sketch the interference patter from six slits • The number of secondary maxima is always N– 2 where N is the number of slits • Because N = 6, the secondary maxima are 1/36 as intense as the primary maxima.

  6. Material for the 2nd Midterm • Material from the book to Study!!! • Objective Questions: 3-6 • Conceptual Questions: 1-3 • Problems: 4-9-11-16-19-21-23
