Treat each of your eyes as a circular aperture of diameter 3.5 mm. Light of wavelength 500 nm is used to view two point sources that are 894 m distant from you.
 
  How far apart must these two point sources be if they are to be just resolved by your eye? Assume that the resolution is diffraction limited and use Rayleigh's criterion.

Question 2

A 0.10-F capacitor is connected to a 120-V rms 60-Hz source. (a) What is its capacitive reactance? (b) What is the rms current to the capacitor? (c) If both the capacitance and the frequency were doubled, what would be the rms current?
 
  What will be an ideal response?
