Multiple Choice
A Young's double-slit experiment is performed in air and then the apparatus is submerged in water.What happens to the fringe separation,and what can be used to explain the change,if any?
A) The separation stays the as it is the same experiment independent of the medium.
B) The separation decreases because the frequency of the light decreases in the water.
C) The separation increases because the wavelength of the light increases in the water.
D) The separation decreases because the wavelength of the light decreases in the water.
