A light source, which emits two wavelengths 
1 = 400 nm and 
2 = 600 nm, is used in a Young ’ s double slit experiment. If recorded fringe widths for 
1 and 
2 are 
1 and 
2 and the number of fringes for them within a distance y on one side of the central maximum are m 1 and m 2 , respectively, then
A
2 > 
1
B
m 1 > m 2
C
From the central maximum, 3 rd maximum of 
2 overlaps with 5 th minimum of 
1
2 overlaps with 5 th minimum of 1
D
The angular separation of fringes for 
1 is greater than 
2
1 is greater than 2
