Briefly state one characteristic of single-slit /double-slit/diffraction grating interference pattern that allow you to clearly distinguish one from the others.
The Attempt at a Solution
Taller, broader central maximum.
More intense, narrower central maximum that single-slit interference.
Less intense, broader (than grating), equally spaced maxima.
Narrow, tall maxima. Broader minima.
I don't think my answers are complete or correct or if they answer the question properly. I also have trouble understanding the reasons why those differences occur.
