In a two-slit interference pattern, if the distance between the slits is increas

In a two-slit interference pattern, if the distance between the slits is increased, what happens to the number of visible fringes on the screen?

In a two-slit interference pattern, if the distance between the slits is increased, what happens to the number of visible fringes on the screen?

Step 1: Understand that in a two-slit interference pattern, light waves from two slits create bright and dark bands called fringes on a screen.
Step 2: Know that the distance between the slits is represented by 'd'.
Step 3: Realize that increasing the distance 'd' between the slits affects the spacing of the fringes.
Step 4: Learn that when 'd' increases, the width of each fringe (the distance between bright or dark bands) decreases.
Step 5: Understand that if the fringe width decreases, it means that the fringes are closer together.
Step 6: Conclude that with the fringes being closer together, there will be fewer visible fringes on the screen within the same distance.
