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 decrease the angular position of the m = 3 minimum of the pattern (more than one answer may be correct)? use light with a longer wavelength O 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 increase the distance along the screen between the pattern's center and the m4 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 screern use slits which are farther apart use slits which are closer together

Explanation / Answer

here d is the slit separation and lamda is the wavelength

a) use light with a shorter wavelength

use slits which are farther apart

for mth bright fring, d*sin(theta) = m*lamda
here d is the slit separation and lamda is the wavelength

b) use light with a longer wavelength

use slits which are close together
