Critics of copernicus's heliocentric cosmos argued that, if earth moves around the sun, our moon would get left behind. which of galileo's observations countered that argument? (a) jupiter's moons stay with jupiter as it moves through space (b) venus and mars stay with earth as it moves through space (c) mars has an elliptical orbit (d) the moon's gravity is too strong for it to get left behind (e) the sun's gravity is too weak to pull the moon from earth

The goal of this experiment was to answer the question, "how does diffraction occur? " suppose you formulated this alternate hypothesis: if the gap width is increased while keeping wavelength constant, then the observed diffraction will decrease because the less the ratio between wavelength and gap width is, the smaller the observed diffraction angle will be.to test this hypothesis, you would change the  gap widthdiffraction anglewavelength  and observe the  gap widthdiffraction anglewavelength  in the system.therefore, the independent variable would be the  gap widthdiffraction anglewavelength  and the dependent variable would be the  gap widthdiffraction anglewavelength.
