Solution: Using the diffraction formula for a single slit of width a, the nth dark fringe occurs for, a sin. θ. = nλ. At angle θ=30°, the first dark fringe is located. Using n=1 and. λ = 700 nm=700 X 10⁻⁹m, a sin 30°=1 X 700 X 10⁻⁹m.
WebThe geometric shadow is the shadow that would have been cast if diffraction effects didn’t happen. It’s a small but important distinction in geometric optics. Diffraction affects the edges of shadows. You have to … WebWe know light diffracts into the geometrical shadow, and as a result the "diffraction pattern/shadow" extends beyond the geometrical edge of each object. That effect can explain many such phenomena. See Spot of …
