Wave Optics question

2022 · 27 Jun · Shift 1 · Q62

JEE MainPhysicsWave OpticsNumerical+4 / −1
In Young's double slit experiment the two slits are 0.6 mm distance apart. Interference pattern is observed on a screen at a distance 80 cm from the slits. The first dark fringe is observed on the screen directly opposite to one of the slits. The wavelength of light will be ‾\underline{\hspace{2cm}}​ nm.
