To calculate the diffraction pattern for two (or any number of) slits, we need to generalize the method we just used for a single slit. That is, across each slit, we place a uniform distribution of point sources that radiate Huygens wavelets , and then we sum the wavelets from all the slits.

Example 14.1: Double-Slit Experiment Suppose in the double-slit arrangement, d =0.150mm, L =120cm, λ=833nm, and y =2.00cm . (a) What is the path difference δ for the rays from the two slits arriving at point P? (b) Express this path difference in terms of λ. (c) Does point P correspond to a maximum, a minimum, or an intermediate condition?
Young’s double slit experiment gave definitive proof of the wave character of light. An interference pattern is obtained by the superposition of light from two slits. There is constructive interference when d sinθ = mλ(form = 0, 1, −2, 2, −2,...) d sin. .

Basic setup for Fraunhofer diffraction through a double-slit. The factor \((\sin\beta/\beta)^2\) in intensity in Eq. (51.5.1) comes from the diffraction of the waves originating from the same slit and the factor \(\cos^2\alpha\) arises from the interference of the waves originating from two different slits.
Learn how interference and diffraction combine to form a complex pattern on the screen for two slits of finite width. Find the formula for the diffraction pattern and the relative intensities of the fringes, and explore the effects of slit width, separation and wavelength.
