Alight source of 460 nm wavelength illuminates a single slit of width 2.80×10−2 mm , producing a standard diffraction pattern on a screen, in which the intensity is 1.03×10−4 w/m2 at the very center of the pattern (θ= 0∘). at a point on the screen for which θ = 1.20 ∘, determine the intensity. express your answer to three significant figures and include the appropriate units.
