question mark

In a single slit diffraction pattern , consider the wavelength is λ and the point
on the screen is 70 away from the central maximum. If the total phase difference
between wavelets from the top and bottom of the slit is 66 rad, then the width of
the slit

let l be the wavelength of light wave
pi=3.14
phase difference =2pi/l *path difference
where path difference is dx/D
here d is the slit separation
and D is the distance between slit plane and screen
As u did not mention the units correctly I m not giving numerical answer
