In two separate experiments monochromatic light is incident on a single slit. The diagrams show the diffraction patterns obtained on a screen far from the slit. In the top diagram the wavelength of light is ${\lambda _1}$ and the slit width is ${b_1}$. In the bottom diagram the wavelength of light is ${\lambda _2}$ and the slit width is ${b_2}$.

In each experiment the distance between the slit and the screen is the same. Which of the following may be deduced?

A.     $\frac{{{\lambda _1}}}{{{b_1}}} < \frac{{{\lambda _2}}}{{{b_2}}}$

B.     $\frac{{{\lambda _1}}}{{{b_1}}} > \frac{{{\lambda _2}}}{{{b_2}}}$

C.     ${b_1} < {b_2}$

D.     ${\lambda _1} > {\lambda _2}$
