Monochromatic light of wavelength `5000 Å` is used in YDSE, with slit width, `d = 1 mm`, distance between screen and slits, `D = 1 M`. If intensites at the two slits are `I_1 = 4I_0 and I_2 = I_0`, find:
a. finge width `beta:`
b. distance of 5th minima from the central maxima on the screen,
c. intensity at `y = (1)/(3) mm,`
d. distance of the 1000th maxima, and
e. distance of the 5000th maxima.

Explanation

Highest order maxima
`n_("max")=[(d)/(lambda)]=2000`
Hence, n = 5000 is not possible.
