A double$-$slit pattern is obtained using monochromatic light. Consider the following five possible changes in conditions:

$1.)$ decrease the wavelength

$2.)$ increase the wavelength

$3.)$ increase the width of each slit

$4.)$ increase the separation between the slits

$5.)$ decrease the separation between the slits

Which of the above would increase the spacing of the interference fringes?

$1$ and $3$ only

$5$ only

$1$ and $5$ only

$3$ only

$2$ and $5$ only
