If you increase the number of slits in a grating while keeping the spacing the same, does each of the following (1) the spacing between intensity maxima, (2) the intensity of the maxima, and (3) the width of the maxima increase, decrease, or remain unchanged?
Understand the Problem
The question is asking about the effects on the interference pattern when the number of slits in a grating is increased while the spacing remains the same. Specifically, it inquires about whether the spacing between intensity maxima, the intensity of the maxima, and the width of the maxima will increase, decrease, or remain unchanged.
Answer
Spacing remains unchanged, intensity increases, width decreases.
The spacing between intensity maxima remains unchanged, the intensity of the maxima increases, and the width of the maxima decreases.
Answer for screen readers
The spacing between intensity maxima remains unchanged, the intensity of the maxima increases, and the width of the maxima decreases.
More Information
Increasing the number of slits leads to sharper maxima due to increased constructive interference, while the overall pattern's spacing remains determined by the slit separation.
Tips
Assuming the slit spacing changes with the number of slits is a common mistake, but it remains constant in this scenario.
