An experiment using a diffraction grating with a monochromatic light source is performed to create an interference pattern on a screen. Consider the following changes: I. Increase the line density of the grating. II. Decrease the frequency of the source. III. Increase the distance to the screen. Which of these changes would cause the pattern to spread out? a) I only b) III only c) I and III only d) I, II, and III e) None of these changes would cause the pattern to spread out.
