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 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 = 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.
