Please show formula and units

For the figure shown below, let R = 1.20 m and d = 0.120 mm and assume the slit system is illuminated with monochromatic 500 nm light. The first bright fringe (m = 1) happens at point P. Calculate the phase difference (ϕ) between the two wave fronts arriving to point P in radians when: 

a) θ = 0.500

b) y = 5.00 mm. The value of θ in part b is not the same as the value of θ from part a.  However, you may assume that θ in part b is small.
