# In the Young’s double slit experiment, if the separation between the slits is 0.5 mm

In the Young’s double slit experiment, if the separation between the slits is 0.5 mm the slit-screen separation is 50 cm, then the fringe width of the interference pattern (l=5×10^{-5} cm) is:

(a) 5×10^{-1} cm

(b) 5 x a0^{-2} cm

(c) 5 x a0^{-3} cm

(d) 5 x a0^{-4} cm
