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?

Ablock of mass m slides on a horizontal frictionless table with an initial speed v0 . it then compresses a spring of force constant k and is brought to rest. the acceleration of gravity is 9.8 m/s2. how much is the spring compressed x from its natural length? 1) x = v0*sqrt(k/(mg)) 2) x=v0*sqrt(m/k) 3) x=v0*((mk)/g) 4) x=v0*sqrt(k/m) 5) x=v0*(m/kg) 6) x=v0*sqrt((mg)/k) 7) x=(v0)^2/(2g) 8) x=v0*(k/(mg)) 9) x=(v0)^2/(2m) 10) x=v0*((mg)/k)
