Expert Solution

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 )
