A pinhole camera has a small circular aperture of diameter D. Light from distant objects passes through the aperture into an otherwise dark box, falling on a screen at the other end of the box. The aperture in a pinhole camera has diameter D = 0.600 mm. Two point sources of light of wavelength 485 nm are at a distance L from the hole. The separation between the sources is 2.70 cm, and they are just resolved by the camera. What is L?
