Multiple Slit Intereference
Question 1
How does the intensity of the primary maxima vary with N?
It varies as the square of the number of slits.
Question 2
How does the number of secondary maxima vary with N?[br]
The number of secondary maxima equals N-2.
Question 3
What happens to the width of the primary maxima as N increases?[br]
It gets narrower in fact the width is proportional to 1/N.
Question 4
What effect does varying the slit width, a, have on the interference pattern?
The single slit diffraction patterns modulates the multiple slit diffraction pattern.
