Only bright fringes.

Circular rings.

Random light spots.

Bright and dark fringes.

The width of the central maximum decreases.

The width of the central maximum increases.

The width of the central maximum remains unchanged.

The width of the central maximum becomes zero.

$\theta = \arcsin\left(\frac{a}{\lambda}\right)$

$\theta = \frac{a}{\lambda}$

$\theta = \arcsin\left(\frac{\lambda}{a}\right)$

$\theta = \frac{\lambda}{a}$

Additional slits shift maxima towards central maximum, concentrating them around normal incidence because more pathways interfere constructively near this angle.

More slits result in fewer but brighter maxima since destructive interferences increase outside main directions enhancing contrast with adjacent dark bands.

Increasing slits narrows and sharpens maxima while their positions remain unchanged as they are determined by wavelength and slit spacing only.

Adding more slits causes maxima to spread out further apart while also becoming less intense due to increased pathway differences among beams from individual slits.

Increases decrease since shorter lead unstable phasing obscuring definitions.

Decreases unchanged means stability doesn't affect clarity.

Remains same because unrelated factors dictate observability.

They increase because longer coherences lengths mean stable phase relationships over greater distances allowing clear fringe definition.

The photon will split into two and pass through both slits simultaneously as classical particles would.

The photon will be absorbed by the material of the slits, preventing any pattern formation.

The photon will pass through one slit but can create an interference pattern over time with successive photons.

The photon will bounce off the slits and not create any observable pattern.

The number of secondary maxima increases.

The central maximum becomes wider and less intense.

The central maximum becomes narrower and more intense.

The distance between secondary maxima decreases.
