Explanation:
From the question we are told that
The wavelength of the light is
The distance of the slit separation is
Generally the condition for two slit interference is
Where m is the order which is given from the question as m = 2
=>
substituting values
Now on the second question
The distance of separation of the slit is
The intensity at the the angular position in part "a" is mathematically evaluated as
Where is mathematically evaluated as
substituting values
So the intensity is
