Light with =600nm falls on the thin soap film (shaped as a wedge) at the angle =30 degrees to normal. Interference fringes are observed in reflection. Distance between adjacent fringes is x=4 mm. Index of the film n=1.33, Calculate angle  of the wedge.

The pressure, volume, and temperature of a mole of an ideal gas are related by the equation pv = 8.31t, where p is measured in kilopascals, v in liters, and t in kelvins. use differentials to find the approximate change in the pressure if the volume increases from 14 l to 14.6 l and the temperature decreases from 375 k to 370 k. (round the answer to two decimal places.)
