why is impssible to locate with certainty both where an electron is and where it's going to be at next moment?

Question

No rubbish wanted exact and precis

Answer 1

an electron is a mobile subatomic particle, you know. as it is very light it can easily be accelerated. according to Heisenberg's Uncertainity Principle, "it is impossible to locate the position and momentum of any subatomic particle simultaneously and precisely".although it is possible to detect an electron's position and momentum simultaneously by using some techniques, but the result won't be precise(exactly correct) ever.to understand this, suppose we direct a beam of massless radiation like gamma ar X- rays to the atom concerned.now the shadow of the eletron will be cast on the photographic plate and its velocity at that instant can also be measured.but X-rays being highly energetic will change the electron's ENERGY(thus velocity), and thus momentum.as such the velocity of electron obtained won;t be its genuine but changed velocity.so simultaneous knowledge of genuine position and momentum of an electron is not possible.
AND IF ONE WANTS TO PROVE HEISENBERG'S THEORY WRONG, THEN HE WILL HAVE TO USE MASSLESS AND ENERGYLESS SOURCE WHICH CAN BE DIRECTED ON TO THE SUBATOMIC PARTICLE, SUCH THAT ITS ORIGINAL POSITION AND VELOCITY ARE OBTAINED(OR VIEW IT WITH NAKED EYES!).
BYE.

Answer 2

Do not drive or operate machinery while reading this article!

My way of stating the Heisenberg Uncertainty Principle is that you cannot know the both the position and velocity at the same time.

I think of a camera, trying to take a picture of something moving, say a football being kicked. If I set the camera to a fast shutter speed, I can take an exact image, freezing the ball in place. I can measure exactly where the ball is, but I can't tell if it's a soft kick or a hard one.

Or, I could set the camera to a slow shutter speed, and measure how much blur the football makes. That would tell me how fast the football was moving.

Now a football travels in a straight line, but an electron doesn't. So when you take that blurry picture of an electron, you can't know where it was at any given point in time. You only know where was at SOME point in time.

This produces the principle. You can take only one picture at a time, know only one piece of information at a time.

Ain't physics fun?

Answer 3

The most common explanation is that measuring an electron effects its momentum and/or location, but that is a misconception. When Heisenberg came up with his theory, it applied even to hypothetical measuring devices with perfect accuracy and no effect on the particles.

Uncertainty deals more with the fact that an electron is not a point or a wave, but more of a wave-particle duality and a probablity function. Any observation that determines either a position or a momentum of such a waveparticle to arbitrary accuracy - known as wavefunction collapse - is subject to the condition that the width of the wavefunction collapse in position, multiplied by the width of the wavefunction collapse in momentum, is constrained by the principle to be greater than or equal to Planck's constant divided by 4π.

Basically, the more acurate you try to get with one, the less accurate you will get with the other.

Answer 4

Heisenberg's uncertainty principle states that one can not find both the position and the momentum of a body with at most certainty , have you heard of quantum mechanics , it revolves around the principle of certainty of finding particles . Let us come back to the question ,electron has dual property meaning it has both particle and wave nature , and it moves at very high speeds , since it has wave nature it can move in high speeds combine it with the speed , thus in second it moves so fast that it is like saying it exists in two places at the same time and so if you know that an electron exists at acertain place at one moment you cant know where it is going to be in the next with at most presition

Answer 5

To locate an electron precisely, you throw light on it. Light means photons which ahve energy. These photons strike the electron and transfer their energy to the electron hence changing its speed. Now the precision in locating the electron is a function of the wavelength of light thrown on it. Greater the wavelength, smaller the precision in location.
Now the point is that if you throw light of small wavelength, you determine the position precisely but small wavelength implies high energy, hence the speed of electron changes so much that you cannot determine the velocity accurately.
When you use light of larger wavelength, position cannot be precise, but the velocity does not change much and hence is precise.
This whole thing is called Heisenberg's uncertainity principle.

Answer 6

This is known as uncertainity principle upon which the entire quantum mechanics spin. To locate an electron (under microscope) light is to be focused upon it. But light (photon) is a pack of energy which will displace the electron as soon as it falls on the electron. Hence it is not possible to predict with certainity the location and momentum of an electron at the same time

Answer 7

this obviously pertains to heisenberg's uncertainty principle as every one here has answered.
the principle states:
delta p * delta x is greater than or equal to h/4 pie
this applies to all bodies, large or small as all of them are supposed to be wave-particles.
here p stands for momentum ie mass * velocity, it is usually smaller for a small sized particle and vice versa.
so. if p for a body is small, the x will be large and vice versa.
for an electron, it has a very small size and thereby a gr8 velocity, so , if u know the velocity, the uncertainty [ represented by h/ 4 pie ] will be very large an dhence u wont be able to find the electron in a specific position.

contrastly a large body has a lesser uncertainty of position and has a predominantly particle nature thereby.

Answer 8

this is because the electron has both a wave nature (behaves like a wave) and particle nature ( behaves like a particle) , this is known as the dual nature in general the electron does not remain at rest and keeps on moving all the time this movement is wave like and very swift and fast and hence the shift in the position of the electron is very fast and we cannot predict the exact position of the electron

Answer 9

what all others hav answered i want 2 add on to that

to locate an electron u need 2 throw light on it .
dimensions of the light must b similar 2 that of the electron. i.e. very small.

small wavelength light.
E=hv
E=h divided by lambda(wavelength)

the wavelength 2 b thrown is small

Energy gets enlarged.
large energy displaces the electron frm its path.
n u cant locate it anymore.

thats the way

Answer 10

For some there are various such moments. Moments once you comprehend that what you're approximately to do is the two the superb component or the worst component which you would be able to do. The question is; "Do you have the braveness to act consequently?"
