Tutor description

1.In the young’s double slit experiment, the interference pattern is found to have an intensity ratio between bright and dark fringes as 9. This implies that (a) the intensities at the screen due to two slits are 5 unit and 4 units respectively (b) the intensities at the screen due to two slits are 4 units and 1 unit respectively
