A thin beam of light of wavelength 50 μm (in the infrared portion of the em spectrum) goes through a thin slit and falls on a screen 3.00 m past the slit. You observe that the first completely dark fringes

occur on the screen at distances of ±8.24 mm from the central bright fringe, and that the central bright

fringe has an intensity of I0 at its center. (a) How wide is the slit? (b) What is the highest order fringe

this scenario is capable of producing? (c) What is the intensity of light at a point on the screen that is

one-quarter of the way from the central bright fringe to the first dark fringe?

Arescue plane flying horizontally at spots a survivor in the ocean directly below and releases an emergency kit with a parachute. because of the shape of the parachute, it experiences insignificant horizontal air resistance. if the kit descends with a constant vertical acceleration of, how far away from the survivor will it hit the waves?
