In an experiment to measure the wavelength of light using a double slit, it is found that the fringes are too close together to easily count them.To spread out the fringe pattern, one could:
A)halve the slit separation
B)double the slit separation
C)double the width of each slit
D)halve the width of each slit
E)none of these
