Screen DlF'actec' xrays Distance 0 Flgure 3: Experimental geometry. 3.2 Interference pattern created by two parallel segments What would be the interference pattern (again, along the Z-axis) created by two horizontal parallel opaque segments separated by a distance a' (this distance is counter from the centre of the first segment to the centre of the second one)? Indicate on your drawing the position at which the first diffraction peak is found (excluding the central peak found at Z = 0), and give the formula relating this position to a', ,1 and D. Winter 2022 Page 4 3.3 Interference pattern created by a series of parallel segments What would be the interference pattern created by a large series of parallel segments spaced by a distance d' (again, counting this distance from the centre of a segment to the centre of the next one)? Indicate on your drawing the position at which the first diffraction peak (again, excluding the central peak) is found, and give the formula relating its position to d', 21 and D
