Double slit experiment :- It shows basically the wave nature of Light, as the the waves passes through slits, its wavefronts collides and at some points, It inductive inteference and at some point destructive interference And produces dark and white spots at each (Lambda D/ d distance) Lambda : Wavelength of light D : Distance of slit from wall d: distance between slits
The phenomenon you're referring to is called the "observer effect," which is often misunderstood. In the context of quantum mechanics, observing a particle can indeed affect its behavior, but it's not accurate to say that light changes its nature in the presence of an observer. Instead, the act of measurement interacts with the particle, altering its quantum state. This is a complex topic involving wave-particle duality and the inherent uncertainty of quantum systems. ~Chat gpt
this statement actually changed the way i used to see it.... but wait what u claim is that the measurement interacts with the particle alter the quantum state of particle does not make sense in any way. in physics, we don't just utter everything being told to us each set up of this experiment can't be claimed to have an measurement error...
It's indeed related to the act of measurement and NOT the act of Observing it. For measuring anything, you need light to bounce off the thing to your eyes. In Quantum Realm, Particles (quantum particles) possesses an energy that is equal or less than the energy required to change their state of existence, thus when any quantum particle is measured - the light (photons) hits the particle and changes its state of existence and collapses its wave function (quantum state), and thus reduces the "determinism" while measuring a quantum particle. "The act of seeing a quantum particle prevents you from seeing it"
I am watching Antrix TV from two years..now these...Experimental discussion wil be better then theoretical discussion..... Very nice Kaushik bhai...we need more such videos... 👍❤👍🙃🙃
I learned this Experiment theory in just 3 months ago in our 12 th hsc syllabus. I think if you post this video some months before might be it was helpfully to me
Huygen is the real originator of Wave theory of light....his only mistake that he considered light as mechanical waves (which needs medium), but in actual light can travel through vaccum also...so his theory was denied by everybody and after YDSE, it was proved that light also showed wave nature.....Infact , photo electric effect strongly supported particle nature while polarisation, and experiments like YDSE supported wave nature
ether medium bhi deny hogaya tha huygen ka , aurr wavefront k backward main intensity kyon zero hoti thi woh bh explain nahin kar paye the woh , ye do chizz unki khudki hypothesis thi jo woh khud explain nahin kar paye isliye normal log unki theory ko believe nahin kiye as woh sab newton ko bhagwan mante the
Ye same cheez 12th me bhi hai.......bhot intresting topic hai kassam se Like isme thoda bhot class 11th ka wave use hota hai.....jaise constructive interference aur destructive interference......agar koi bacha science se door bhagta hai to ek baar iss chapter ka intro dekhna Wave optics ia one of my fav chapters😅.......

For macro (big that can be seen with naked eyes) particles light behave like particle in nature but for micro (small that cannot be seen with naked eyes) particles light behave like wave in nature
#Question Sir , according to quantum eraser experiment when we observe a light it shows its particle nature but in this video camera and your self is observing the light hence, light should be shows its particle nature but we have seen it's wave nature. How does it possible ? Why light doesn't shows its particle nature ? And also what is the difference between measuring device(used in Young's experiment) and observer(in this case you and a camera) ? Please explain !!!!!
He is watching it as whole but if you see light from slits then it will show particle nature, as shown in the video the observer is near slits when light showed particle nature.
Basically light is an matter wave (not an em wave) Which means that photon particle is showing wave like nature itself just as what we saw in the water experiment So photon is Basically moving like a wave having crest and troughs That's why it can show both nature Every stuff around us has wave wave nature it's just that the wavelength is negligible neglecting its wave nature Cuz of wavelength=h/mv and since more the m less the wave nature And that's why at small scale such as photon and electron they show significant wave nature.
Good assumption👍👍👍 Just need experiment to prove Wheter light is em wave is proven by maxwell as em wave have same speed But also when photon is observed is behave as particle
It's not the point of argument The point is that in YDSE when a measuring device is installed then the light shows particle nature. Which is the measuring device used?

💥💢💢Alert -Actually there is a problem in this explanation sir, Jo dual nature ki app bat kar rahe ho vo light me to hota hai but double slit ke observer se koi farak nahi padta.Jab camera se apne wave record kiya tab bhi to vo wave dikhaya tha. In fact,observer par state ELECTRON ki depend karte hai jo observe karne se particle and wave when not observing ho jata hai.
I also read it somewhere: "To demonstrate this phenomenon, the Weizmann Institute built a tiny device, less than one micron in size, that had a barrier with two openings. They then sent a current of electrons towards the barrier. The observer in this experiment was not human. Instead, they used a tiny electron detector that could spot the presence of passing electrons. The quantum “observer’s” capacity to detect electrons could be altered by changing its electrical conductivity, or the strength of the current passing through it. Apart from “observing,” or detecting the electrons, the detector had no effect on the current. Even so, the scientists found that the very presence of the detector “observer” near one of the openings caused changes in the interference pattern of the electron waves passing through the openings of the barrier. In fact, this effect was dependent on the “amount” of observation: when the “observer’s” capacity to detect electrons increased, in other words, when the level of the observation went up, the interference weakened; in contrast, when its capacity to detect electrons was reduced, and the observation slackened, the interference increased. Thus, by controlling the properties of the quantum observer, the scientists managed to control the extent of its influence on the electrons’ behavior!"
Agar superposition principle ke hisaab se dekhein , jaisa aapne apni picchli video mei btaya tha , ki jab aap uss exp ko observe krenge to light particle nature ko follow kregi or sirf ek hi maxima dikhega , yehi mujhe vo video mei bhi smjh ni aaya tha...?Aapki observation se frk kyu nhi pda pr measuring device se hi frk kyu pda... or agar measuring device se kaam nhi hua to hmare paas readings or formulae kaise aaye?
Very interesting video. I have a doubt, in your experiment you were watching & recording the laser rays passing through the hair (slit), but still it was showing wave behaviour ! Please explain
Bhaiya bachho ko pagle mat banao samjhane ke liye, light concious thodi hai jo apni marzi behaviour change kar le. Asli me vo measuring device hamari aank ki tarah light ko nahi dekta , usse interact karne ki vajah se light ka particle type behaviour dekhe ko milta hai. Asli mein toh light na particle hai na wave hai vo inse koi alag hi chij hai. Light is like god, present everywhere at the same time.
Measuring device ke baare mein aur batao... How does it measures? If that device looks directly into the incoming light, then incoming light will never reach the screen. Then how does it measures the light ?
Single hair will give you a diffraction pattern. Single hair can't work as a double slit for light. You are showing a diffraction pattern using yiur hair. For double slit experiment using light, you should have two very small holes/openings separated by a very small distance and then you will get doible slit interference pattern on screen.

That's not watch, observation means detecting with electromagnetic detectors on the slits
This is a consequence of one of the most fundamental principle of Quantum mechanics , Heisenberg uncertainty principle.
@@blhfos4101 no one ever really shown it

Wave Particle Duality Of QUANTUM WORLD EXPLAINED CLEARLY❤❤

So photon is Basically moving like a wave having crest and troughs

Cuz of wavelength=h/mv
and since more the m less the wave nature
And that's why at small scale such as photon and electron they show significant wave nature.
But not when they are observed
Good assumption👍👍👍
Just need experiment to prove
Wheter light is em wave is proven by maxwell as em wave have same speed
But also when photon is observed is behave as particle
It's not the point of argument
The point is that in YDSE when a measuring device is installed then the light shows particle nature.
Which is the measuring device used?
Yes this is thought in jee chemistry class 11th that all the particles have wave nature less the mass of particle more the wave nature.
