For the double slit experiment, we use two lasers of different
wave length. Which statement is true for the laser with the longest
wavelength?
a) diffraction and interference are closer together than with
the shorter wavelength laser
b) diffraction and interference are further apart than with the
shorter wavelength laser
c) diffraction is closer together and interference is farther
apart than with the shorter wavelength laser
d) diffraction is farther apart and interference is closer
together than with the shorter wavelength laser
