Laser light sent through a double slit produces an interference pattern on a screen 3.0 m from the slits. If the second order maximum occurs at an angle of 12.0, at what angle does the eighth order maximum occur?
The inside of the cylindrical can shown above has cross-sectional area 0.005 m^2 and length 0.15 m. The can is filled with an ideal gas and covered with the loose cap. The gas is heated to 363K and some is allowed to escape from the can so that re..
