Directions: The following figure shows an experimental arrangement given by Fresnel. It consists of two plane mirrors inclined at an angle of 12 minutes of arc. The distances from the mirrors' intersection to the side 'S' and the screen are 10 cm and 130 cm, respectively. The wavelength of light in Fresnel double mirrors can be looked upon as modified YDSE. Here, the two coherent sources are virtual and mirror images of S. Interference is obtained due to reflected light from the two mirrors. Interference pattern consists of alternate bright and dark fringes similar to YDSE, but with a difference that interference pattern is limited to overlapping region. Fringe width and position of maxima and minima is given by similar expression as in YDSE.



The number of possible fringes formed on the screen is
