Part C 0.175 m MgF2 Calculate the boiling point of the solution in part C, assuming complete dissociation.
Two slits separated by a distance of d = 0.175 mm are located at a distance of D = 2.01 m from a screen. The screen is oriented parallel to the plane of the slits. The slits are illuminated by a monochromatic and coherent light source with a wavelength of λ = 604 nm. A wave from each slit propagates to the screen. The interference pattern shows a peak at the center of the screen (m=0) and then alternating minima...
