JEE AdvancedPhysicsWave OpticsMultiple correct+3 / −1

A light source, width emits two wavelengths

\lambda

1 = 400 nm and

\lambda

2 = 600 nm, is used in a Young's double-slit experiment. If recorded fringe widths for

\lambda

1 and

\lambda

2 are

\beta

1 and

\beta

2 and the number of fringes for them within a distance y on one side of the central maximum are m1 and m2, respectively, then

A
$\beta$ 2 > $\beta$ 1
B
m1 > m2
C
from the central maximum, 3rd maximum of $\lambda$ 2 overlaps with 5th minimum of $\lambda$ 1
D
the angular separation of fringes of $\lambda$ 1 is greater than $\lambda$ 2
