Answer the following question given this paragraph: 

27.5 Single Slit Diffraction Light passing through a single slit forms a diffraction pattern somewhat different from those formed by double slits or diffraction gratings. Figure 27.21 shows a single slit diffraction pattern. Note that the central maximum is larger than those on either side, and that the intensity decreases rapidly on either side. In contrast, a diffraction grating produces evenly spaced lines that dim slowly on either side of center.


Q: What kind of lines does a diffraction grating produce?

 Choices:

- nearly spaced lines

- properly spaced lines

- randomly spaced lines

- evenly spaced lines

A:
evenly spaced lines
