2Chapter 37: Interference of Light Waves: Examples
3Example 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
4Example 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.
5Example 37.3 Six slits (Quiz 37.2) Sketch the interference patter from six slitsThe number of secondary maxima is alwaysN – 2 where N is the number of slitsBecause N = 6, the secondary maxima are 1/36 as intense as the primary maxima.
