Question

1. You observe two point sources of light that are spaced 10 cm apart which are each emitting light of wavelength of 590 nm. If the diameter of your pupil is 2 mm, how distant can the objects be from your eye for you to just barely resolve them

2. Light traveling in air (index of refraction 1.00) falls onto a thin plastic film (index of refraction 1.30) of unknown thickness that covers glass (index of refraction 1.50). What minimum non-zero thickness is needed such that wavelengths of 650 nm in air are bright in the reflection

3. Light traveling in air (index of refraction 1.00) falls onto a thin film (index of refraction 2.60) of unknown thickness that covers glass (index of refraction 1.50). What minimum non-zero thickness is needed such that wavelengths of 550 nm in air are canceled in the reflection
