Model the pupil of the eye using a single slit. If the eye is able to notice changes in intensity of 20% show that it can distinguish two objects seperated by an angle of 0.00015 radians if =500nm and diameter=4mm.

2. Relevant equations

I=Iosin^2((π/λ)asinθ)/ ((π/λ)asinθ)^2

sin θ=λ/a

3. The attempt at a solution

I attempted to find a (width) from the intensity equation but it doesn't seem to work, so Im unsure of how to start the calculation, the question is worth 4 marks, any help would be appreciated :)
