In a Young's double slit experiment, $\displaystyle 16$ fringes are observed in a certain segment of the screen when light of wavelength $\displaystyle 700$ nm is used. If the wavelength of light is changed to $\displaystyle 400$ nm, the number of fringes observed in the same segment of the screen would be :
Official answer
(3)
$\displaystyle 28$
