In Young's double-slit experiment, the slits are 2 mm apart and are illuminated by photons of two wavelengths \(\lambda_{1}\) = 12000 \(\overset \circ{A}\) and \(\lambda_{2}\) = 10000 \(\overset \circ{A}\) . At what minimum distance from the common central bright fringe on the screen 2 m from the slit will a bright fringe from one interference pattern coincide with a bright fringe from the other?
- 8 mm
- 6 mm
- 4 mm
- 3 mm
Answer
(B) 6 mm
