Light from a 600 nm source goes through two slits 0.080 mm apart. What is the angular separation of the two first order maxima occurring on a screen 2.0 m from the slits

The angular separation is  

Explanation:

From the question we are told that

   The  wavelength of the light is

   The  distance of separation between the slit is  

    The distance from the screen is

Generally the condition for  constructive interference is mathematically represented as

=>    

    here is the angular separation between the central maxima and one side of the first order maxima

given that we are considering the first order of maxima n =  1  

        =>  

        =>    

        =>  

So the angular separation of the two first order maxima  is
