###### Problem Details

Consider a telescope with a small circular aperture of diameter 2.0 centimeters.

Part A: If two point sources of light are being imaged by this telescope, what is the maximum wavelength λ at which the two can be resolved if their angular separation is 3.0×105 radians?

Part B: Calculate the angular separation θ1 at which two point sources of wavelength 600 nanometers are just resolved when viewed through a circular aperture of diameter 1.5 centimeters.
