The diffraction pattern shown in FIGURE 28-49 is produced by passing He-Ne laser light (λ = 632.8 nm) through a single slit and viewing the pattern on a screen 1.50 m behind the slit.

(a) What is the width of the slit?

(b) If monochromatic yellow light with a wavelength of 591 nm is used with this slit instead, will the distance indicated in Figure 28-49 be greater than or less than 15.2 cm? Explain.

In figure 28-49
