In our experiment we used very narrow slits (where the length of the slit is much larger than the width) to produce a diffraction pattern that spanned horizontally (perpendicular to the length of the slit). Which answer best describes how the diffraction pattern would be different if d was doubled?

Assume that a person skiing high in the mountains at an altitude of h = 15100 ft takes in the same volume of air with each breath as she does while walking at sea level. determine the ratio of the mass of oxygen inhaled for each breath at this high altitude compared to that at sea level. assume that the air composition (i. e. % of air that is oxygen) is the same at sea level as it is at 15100 ft.
