A thin beam of light of wavelength 625 nm 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 2.00 W/m2 at its center. (a) How wide is the slit? (b) 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?
On cold days your bedroom window may get wet on the inside. This is because
1) the air near the glass becomes saturated. 2) a change in phase from gas to liquid occurs. 3) H2O molecules release energy when they liquify on the glass. 4) fast-moving H2O molecules slow down and condense when they encounter the cold glass. If the air in the room were colder than the air outside, then quite likely 5) the glass would be even wetter. 6) no wetness would occur. 7) the glass would be wet (or frosty) on the outside surface. 8) none of the above.
