Wave Optics question

2022 · 29 Jun · Shift 2 · Q69

JEE MainPhysicsWave OpticsNumerical+4 / −1
In a double slit experiment with monochromatic light, fringes are obtained on a screen placed at some distance from the plane of slits. If the screen is moved by 5 ×\times× 10 −-− 2 m towards the slits, the change in fringe width is 3 ×\times× 10 −-− 3 cm. If the distance between the slits is 1 mm, then the wavelength of the light will be ‾\underline{\hspace{2cm}}​ nm.
