Answer:

fringes move farther

Step-by-step explanation:

The relation between the distance between the fringes is given by

y = Dλ/d

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.
