In single slit diffraction, light outstretches in a line perpendicular to the slit. What is the difference between single and double slits? When the slit width is doubled, the energy falls per sec on the screen is doubled, but the angular width of the central maxima (Δθ=b2λ) is halved. What happens when the slit width is doubled? The light passing through is diffracted in a pattern the same as a double slit, with bright regions at various angles. It also shows the double-slit diffraction intensity.Ī diffraction grating is a large number of evenly spaced and distributed parallel slits. The double-slit experiment is a demonstration that light and matter can display attributes of both classically defined waves and particles. What does the double-slit experiment show?
