Either light has a split personality, particle vs wave, either that interference pattern is not really an interference pattern, but a diffraction & reflection pattern or something along those lines. Maybe those black lines are just shadows made by the most probable diffraction points, which cast different shadows.

The bright and dark lines do not appear if source of light is sunlight. Sunlight has almost all the wavelengths while for a clear pattern the beam should be a pure light (only one wavelength)

[@alishbaabbas1210]

Yes light should be monochromatic

U made it so easy to understand.

Too difficult to grasp how a 450 nm wave could have interference of peaks and troughs that show the pattern of what I would think is bi-refringence with dark and bright regions.

[@GamesBond.007]

They now use monochromatic light to get that pattern. Young used sun light which is white light. But now they say white light doesnt clearly show the pattern. This means Young clearly didnt see any pattern, but more like imagined there was one.

[@GamesBond.007]

I dont see either how the interference pattern at such nanoscopic scales would be visible with the human eye !

[@GUPTAYOGENDRA]

In double slit experiment, the conscious observer is not only observing the electron gun, screen containing two slits and detector but also the human body, performing the experiment and thoughts which are forcing the body to act. The conscious observer who is consciousness itself is not observable and hence is observing the entire universe from outside the universe as required by quantum mechanics to collapse the overall wave function of the universe.

[@GamersOfKerala]

u actually gave me the concept

[@GamesBond.007]

What material were the walls ? I imagine that reflection of light between walls can create a similar pattern if they were made of a smooth surface.

[@tawkirahmed2095]

great

[@anjanamathew537]

Good explanation... But Is this possible with sunlight...?

[@WilliamMcCormickJr]

Light inverts through a slit. Just like through a camera lens, or a convex lens at a distance. That is what is not being discussed. Sincerely, William McCormick

[@Bangalibabu95]

@@فيزياءالعملية : Yes, Central is maximum, and it keep on diminishing in both the sides. I mean the intensity tends to become less and less, and eventually it disappears.

[@فيزياءالعملية]

@@Bangalibabu95 thanks a lot but why is more brighter? Is this due to interfere crest with crest

By using sunlight we will get colourful band of unequal width... There should be monochromatic light source of light

[@schmetterling4477]

What's wrong with a little color?

[@krivlex8214]

@@schmetterling4477 you will not be able to notice the dark and bright bands formed during the interference, which is the whole point of this experiment. If a monochromatic source of light is used, these fringes can be observed. You will also find that the distance between two consecutive bright or dark bands is λd/D, where d is the distance between two slits and D is the distance of separation of slits from the screen.

[@schmetterling4477]

@@krivlex8214 The whole point of this experiment is to show that light is a wave phenomenon. That can easily be done with polychromatic light.

[@krivlex8214]

@@schmetterling4477 yeah, but the thing is you can't really make out the dark and bright bands. The monochromatic light used makes it easier to prove that light is a wave phenomenon.

[@schmetterling4477]

@@krivlex8214 There is no such thing as monochromatic light. All light has a spectrum with finite width, even if we can make light with a very narrow spectrum. It therefor follows that there is no such thing as a perfect minimum. You have to stop mistaking the absolute predictions of mathematical approximations for necessary scientific criteria. That is not how we do it in physics, even if we simplify it that far at the high school level.

The name of the experiment contains double slit how are you saying pinholes it is conceptually incorrect

[@GamesBond.007]

But why did he put the single slit before the other two ? This makes it a 3 slit experiment, not double slit. These scientists cannot even count, but they know exactly what happens lol.

[@KimKim565]

Is that a bot reading? I really cant tell.

[@ikaeksen]

yes, with hindi accent lol

[@GamesBond.007]

Its TRIPLE SPLIT obviously...and the pattern of interference is most likely just a reflection pattern of photons in between the walls. MYTH BUSTED.

A mistake in 5.16min phase difference formula.take into account please

[@anjanamathew537]

is the correct formula - (2n + 1)lamda /2

[@al1383]

Why would light travel as a wave horizontally, or is it a spiral type wave? And if you adjust the distance of the wall with the light sensors with the wall with the 2 slits can you do so and get a dark spot in the middle of the back wall? If not, why not if the waves are interfering with dark spots between?

Hi sani

They now use monochromatic light to get that pattern. Young used sun light which is white light. But now they say white light doesnt clearly show the pattern. This means Young clearly didnt see any pattern, but more like imagined there was one.

[@Chicken_Little_Syndrome]

"Michelson and Morley (1887) and other early experimentalists using interferometric techniques in an attempt to measure the properties of the luminiferous aether, *used monochromatic light only for initially setting up their equipment, always switching to white light for the actual measurements.* The reason is that measurements were recorded visually. Monochromatic light would result in a uniform fringe pattern. Lacking modern means of environmental temperature control, experimentalists struggled with continual fringe drift even though the interferometer might be set up in a basement. Since the fringes would occasionally disappear due to vibrations by passing horse traffic, distant thunderstorms and the like, it would be easy for an observer to "get lost" when the fringes returned to visibility. The advantages of white light, which produced a distinctive colored fringe pattern, far outweighed the difficulties of aligning the apparatus due to its low coherence length.[23] This was an early example of the use of white light to resolve the "2 pi ambiguity"." - Interferometry, Wikipedia

[@sapangurung5886]

No needof books, building of college, lectures etc

[@omarabdulghani8077]

At point O the fringe that appear it must be the central bright fringe but this video shows that its an bright fringe . Also you say that the width of fringes are equal, while the central bright fringes has a double width of any bright fringes And if the fringe that appear at the point O isn't the central Bright fringe, so where is the central bright fringe Please I want an answer to all of this and to clarify whether what I'm saying an error

[@DOtman2222]

Omar Abdul Ghani this is interference of light where the width of fringes dark or bright are equal whereas in Diffraction of light you get central bright fringe that is double the width of the lateral fringes
