Two wavelengths, 800 nm and 600 nm, are used separately in single-slit diffraction experiments.The diagram shows the intensities on a far-away viewing screen as function of the angle made by the rays with the straight-ahead direction.If both wavelengths are then used simultaneously, which point corresponds to the smallest angle at which the light on the screen is purely 800-nm light?
A)A
B)B
C)C
D)D
