Part A:How far away can a human eye distinguish two car headlights 1.8 m apart? Consider only diffraction effects and assume an eye pupil diameter of 5.5 mm and a wavelength of 550 nm.Part A= L = 1.5 X 10^4 mPart B:What is the minimum angular separation an eye could resolve when viewing two stars, considering only diffraction effects?Part B= Theta = 0.42Part C: In reality, it is about 1' of arc. Why is it not equal to your answer in B? <-- this part is the only one I dont know, I got the other two correct
