The spacing between the adjacent lines of a diffraction grating is the same as the distance between the two slits in the Young's double slit experiment.Both are illuminated by light of the same wavelength.In which way do the interference fringes seen on the screen differ for the two methods?
A)There is no difference in the interference fringes.
B)The fringes from the grating are farther apart.
C)The fringes from the double slit are farther apart.
D)Each of the fringes from the grating is narrower than the double slit.
E)Each of the fringes from the double slit is narrower than the grating.

The diffraction grating produces narrower fringes due to the constructive and destructive interference from multiple slits, leading to sharper and more defined peaks compared to the broader fringes produced by the double slit experiment.
