Determine the maximum distance at which an observer can still distinguish two small bright sources 12.5 mm apart emitting the light of  452 nm, given that the eye pupil size is around 4.0 mm. Give your answer in SI units.

The lens of a giant human eye is about 7.4 cm in diameter. For visible light at 643nm, what is the diffraction limit in arcsec of a giant human eye?

answer please

What is the angular resolution limit (degrees) set by diffraction for the 224-cmcm mirror diameter telescope (λλ=560 nmnm)?

Please refer again to Figure 2.   The incident ray is coming in from water (n=1.33) rather than air. And this time, theta = 52.2 degrees, y = 31.9 cm and h = 1.13 cm. What is x now?       33.6 cm     42.0 cm     12.6 cm     50.4 cm
