It creates an effect known as diffraction, whereby the light waves (or, if you think about it in terms of particles, as light and all other objects for that matter can be thought of as both a wave and a particle (see De'Broglie's wave-particle duality) the relative position of photons over the area where the light passes) spread or disperse. Some would compare it to how people spread in all directions after pushing through a narrow opening such as busy subway trains.
This results in something called interference (caused by the superposition of the waves), which can be constructive or destructive. In the former, the path difference (distance from the crest or trough from one wave to another ie phase) is a multiple of the wavelength, and the wave's amplitude will increase (ie brighter spots/fringes of light). In the latter the opposite happens and dark patches occur (path difference is an odd number of half-wavelengths) since the waves completely cancel each other out.
This is what you see in the screen of the experiment, a pattern of alternated black/light fringes. The middle fringes will have greater intensity and the outwards ones will be less intense.
This experiment has many practical applications in technology which relies on the use of waves and their properties, such as CD reading/writing etc., radio transmission etc. It is also proof that light behaves as a wave and, alongside the photoelectric effect, as a particle as well.

What is the distance from the slits to the screen in the double-slit experiment?
In the double-slit experiment, the distance from the slits to the screen is typically several meters.
What is the difference between the interference patterns produced by a single slit and a double slit in a double-slit experiment?
In a double-slit experiment, the interference patterns produced by a single slit and a double slit differ in their complexity and visibility. The interference pattern from a single slit is a simple pattern of alternating light and dark bands, while the interference pattern from a double slit is a more intricate pattern of multiple bright and dark fringes.
How do reflections affect the interference pattern in a double slit experiment?
Reflections can disrupt the interference pattern in a double slit experiment by causing additional waves to interfere with the original waves, leading to a distorted pattern.
How was the mystery of the double-slit experiment solved?
The mystery of the double-slit experiment was solved by realizing that particles can behave as both particles and waves, depending on how they are observed. This duality is known as wave-particle duality and is a fundamental concept in quantum mechanics.
Has the double slits experiment been debunked?
No, the double slit experiment has not been debunked. It is a well-established and widely accepted experiment in quantum physics that demonstrates the wave-particle duality of light and matter.

What happens when a third slit is introduced in Young's double slit experiment?
Born's rule predicts that interference patterns from three or more slits is equivalent to combining the effects of several double slit experiments. This rule was validated in an experiment done at the University of Waterloo in 2010.
What is the equation in the double slit experiment?
The equation is: nλ=d(x/l) where: n is Order of maxima λ is wavelength d is slit separation x is fringe separation l is distance from screen to double slit

What is the expression for the separation distance between the slits in a double-slit experiment where light waves interfere with each other?
The expression for the separation distance between the slits in a double-slit experiment where light waves interfere with each other is typically denoted by the symbol "d."
How do interference waves affect the propagation of light in a double-slit experiment?
Interference waves in a double-slit experiment cause light waves to overlap and either reinforce or cancel each other out, creating a pattern of light and dark bands on a screen. This interference phenomenon is a key aspect of how light propagates in the experiment.
What are the key findings and implications of Young's double slit experiment?
The key findings of Young's double slit experiment show that light behaves as both a wave and a particle. This duality challenges traditional ideas about the nature of light. The implications of this experiment have had a significant impact on the development of quantum mechanics and our understanding of the fundamental nature of the universe.
What kind of experiment might an physicist perform?
Maybe the double slit experiment in an attempt to solve the standing mystery of wave-particle duality of electrons.http://en.wikipedia.org/wiki/Double-slit_experiment
What is the significance of the double slit experiment in the field of quantum mechanics?
The double slit experiment is significant in quantum mechanics because it demonstrates the wave-particle duality of particles, showing that they can exhibit both wave-like and particle-like behavior. This experiment has profound implications for our understanding of the fundamental nature of matter and the principles of quantum mechanics.
