Question

Two plane mirrors (Fresnel's arrangement)(see figure) are inclined to each other at an angleO and an illuminated slit Sis placed in front of them at a distance 12 cm away from and parallel to the line ofintersection of the mirror. An eyepiece is mounted at a distance 60 cm from the line of intersection of themirrors. If the band-width obtained is 0.16 mm and wavelength of light used is 5460 Å, the value of theta is
