In Young’s double slit experiment, the slits are 2mm apart and are illuminated by photons of two wavelengths $$\lambda_{1}$$ =12000 A and $$\lambda_{2}$$=10000 A. At what minimum distance from the common central bright fringe on the screen 2 m from the slit will a bright fringe from oneinterference pattern coincide with a bright fringe from the other?

A

3 mm

B

8 mm

C

6 mm
