Final answer:

The frequency of light does not affect the number of lines in the interference pattern of Young's experiment; instead, higher frequencies result in narrower spacing between lines, and lower frequencies result in wider spacing. So the correct option is C.

Step-by-step explanation:

The question concerns how the frequency of light affects the interference pattern observed in Young's experiment, which is a classic physics experiment demonstrating the wave nature of light. In Young's experiment, light passes through two closely spaced slits to create a pattern of bright and dark fringes due to interference.

The number of lines in Young's interference pattern is not affected by the frequency of light. Instead, the frequency (or equivalently, wavelength, since they are inversely related) affects the spacing between these lines. Specifically, higher frequencies of light, which correspond to shorter wavelengths, produce narrower spacing between the interference fringes. Conversely, lower frequencies, which correspond to longer wavelengths, produce larger spacing between the fringes. Therefore, the correct answer to the question is option C: higher frequencies have larger spaces between lines. This relationship aligns with the understanding that as the wavelength becomes smaller due to higher frequencies, the patterns of interference become more closely spaced.
