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

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

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

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

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.

The varying intensity emitted by each individual slit.

The scattering of photons by atoms at each slit edge.

Constructive and destructive interference between waves from each slit.

The bending of light rays due to gravity near each slit.

Bright fringe spacing varies greatly since monochromatic implies multiple wavelengths present.

All fringes are equally dim because single wavelength light sources don't produce much intensity on any given point due to lack of variety in wavelengths available for interference purposes.

Bright fringes appear only at the top and bottom of the screen as monochromatic has limited spatial coverage.

Bright fringe spacing will be consistent throughout because monochromatic light has a single wavelength.

No change is observed in the incident waveforms and they still constructively interfere to create an identical, regular, and spatially consistent array of high-intensity spots.

The full waveform shifts towards one source.

The first bright fringe adjacent to either side of the central bright spot shifts halfway towards the next dark spot.

The independent individual source contribution results in an altered interference pattern, even though the composite pattern doesn't alter overall.
