If 735-nm and 620-nm light passes through two slits 0.78 mm apart, how far apart are the second-order fringes for these two wavelengths on a screen 1.0 m away?
Express your answer to two significant figures and include the appropriate units.

Distance between two second order fringes for the two wavelengths ,
Here can be find using below formula
The distance of second order maxima from central maximum,
Where m= 2 for second order maximum
L= distance of screen from slits
d=distance between two slits
Distance between two second order fringes for the two wavelengths is, (upto 2 significant figures )
