A rectangular horizontal hole 0.25mm x 0.75 mm in an opaque screen is illuminated normally by plane waves of blue light of an argon ion laser at lambda=488 nm. The diffraction pattern is cast on a screen in the focal plane of a nearby positive lens (f=2.5m). Describe the resulting central maximum.

This is a Franhofer diffraction problem.

Plane waves of blue light, ℷ = 434 nm, falls on a single slit, then pass through a lens with a focal length of 85.0 cm between the screen and the slit. If the central band of the diffraction pattern on the screen has a width of 2.450 mm, find (a) the width “a” of the single slit. (b) the linear distance from the center of the screen of the first minimum of the diffraction pattern.

If you illuminated a 100 mm focal length lens with a plane wave of 550 nm wavelength through a square aperture at the lens of size 1 cm x 1 cm, what size would the central bright region be of the pattern in the back focal plane of the lens (one focal length behind the lens)?
