MHT CET 2025 22nd April Morning Shift | Wave Optics Question 6 | Physics

In a Young's double slit experiment wavelength of light used is $6000 \mathop {\rm{A}}\limits^{\rm{o}}$. The first order maxima and tenth order maxima fall at 14.50 mm and 16.75 mm from the particular reference point in the interference pattern respectively. If the wavelength is changed to $5500 \mathop {\rm{A}}\limits^{\rm{o}}$ then the position of zero order and tenth order maxima are respectively

[The other arrangements remaining same]

$14.25 \mathrm{~mm}, 16.55 \mathrm{~mm}$

$12.25 \mathrm{~mm}, 14.55 \mathrm{~mm}$

$10.25 \mathrm{~mm}, 12.55 \mathrm{~mm}$

$16.25 \mathrm{~mm}, 18.55 \mathrm{~mm}$ $$\mathop {\rm{A}}\limits^{\rm{o}} $$
