Problem

In a double-slit set-up, the slit separation is

0.25\,\text{mm}

and the screen is

1.5\,\text{m}

away. If light of wavelength

500\,\text{nm}

is used, the distance of the fourth bright fringe from the central maximum on the screen is closest to a)

0.60\,\text{cm}

0.96\,\text{cm}

1.20\,\text{cm}

1.35\,\text{cm}
