Webminima of the diffraction envelope? – 1 fringe in center, 5 on either side, 6 th on either side coincides with 1 st diffraction minimum – bright fringes occur at angles given by dsin θ = m 2λ; diffraction minima by asin θ= m 1λ • at first diffraction min, asin θ= λ and dsin θ= 6 λ, so d/a =6 • at second diffraction min, asin θ ... WebThis is a general property of interference and diffraction: a known wavelength of light can be used to probe the size of a structure or the known dimensions of a diffracting object (in this case the width of the slit) can be used to deduce the wavelength of incident light. We will employ both techniques to make diffraction-based measurements.
