In Young's double slit experiment, width of the second slit is double the width of first slit, consequently the amplitude of the light from two slits. '$I_m$' is the maximum intensity. The resultant intensity '$I$' when they interfere with the phase difference of $\phi$ is given by

$\dfrac{I_m}{9}\left(1 + 8\cos^2\dfrac{\phi}{2}\right)$

$\dfrac{I_m}{7}\left(3 + 5\cos^2\dfrac{\phi}{2}\right)$

$\dfrac{I_m}{5}\left(1 + 2\cos^2\dfrac{\phi}{2}\right)$

$\dfrac{I_m}{3}\left(1 + 6\cos^2\dfrac{\phi}{2}\right)$
