Which statement is true about the picture above?
a) the spheres have only weight but no mass
. b) the 40 newton sphere has the greatest gravitational force. eliminate
c) the smaller the weight, the greater the gravitational force.
d) although the weights of the spheres are different, the gravitational forces are the same.

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.
