Which property is a characteristic of single-slit diffraction but not double-slit diffraction? the central bright band bands are equally spaced bands get thinner farther from the band red light bands are spaced farther from each other than blue light bands

Agas initially at p1 = 1 bar and occupying a volume of 0.5 liter is compressed within a piston–cylinder assembly to a final pressure p2 = 4 bar. (a) if the relationship between pressure and volume during the compression is pv = constant, determine the volume, in liters, at a pressure of 3 bar. (b) repeat for a linear pressure–volume relationship between the same end states. reference
