Question
A pair of slits is located near a screen in such a way that light incident on the slits can form a double slit interference pattern on the screen.
(a) Which of the following actions performed by itself would increase the angular position of the m = 3 minimum of the pattern (more than one answer may be correct)?
use light with a longer wavelength
use light with a shorter wavelength
increase the distance from the slits to the screen
decrease the distance from the slits to the screen
use slits which are farther apart
use slits which are closer together
(b) Which of the following actions performed by itself would decrease the distance along the screen between the pattern's center and the m = 2 maximum of the pattern (more than one answer may be correct)?
use light with a longer wavelength
use light with a shorter wavelength
increase the distance from the slits to the screen
decrease the distance from the slits to the screen
use slits which are farther apart
use slits which are closer together
