A laboratory experiment produces a single-slit diffraction pattern on a screen. If the slit is made narrower, the bright fringes will be A. Closer together. B. In the same positions. C. Farther apart. D. There will be no fringes because the conditions for diffraction won't be satisfied.

option (c)

Explanation:

The relation between the distance between the fringes is given by

where, D is the distance between the plane of slit and the screen

d is the width of slit, λ is the wavelength of light used.

As the slit made narrower, that means d decreases, the value of y increases, that means the fringes move farther.

because it says use -2,0,and 2 for x, we can plug those numbers into the equation. y/4=3/4(-2)+2   y/4= -1 1/2 +2 now to get x by itself, we can multiply each side by 4. y=-6+8 which equals y=2 when x=-2. now you can do the same thing with 0 and 2 as x. you get y=8 when x=0 and y=14 when x=2.

x   |   y

-2 |   2

0   |   8

2   |   14
