What is the smallest possible size something can be?
the Planck Length
The smallest possible size for anything in the universe is the Planck Length, which is 1.6 x10-35 m across.
What’s smaller than Planck length?
Well, there is no “length” smaller than the planck length.
Why is Planck length smallest possible?
So why is the Planck length thought to be the smallest possible length? The simple summary of Mead’s answer is that it is impossible, using the known laws of quantum mechanics and the known behavior of gravity, to determine a position to a precision smaller than the Planck length.
Is Planck length smaller than an atom?
LP = (hG/2πc3)1/2 . This defines the Planck length, which is 1.6 x 10-35 metres. To give you an idea, let’s compare it with the size of an atom, which is already about 100,000 times smaller than anything you can see with your unaided eye (an atom size is about 0.000 000 0001 meters).
What’s the smallest matter?
Quarks are the smallest particles we have come across in our scientific endeavor. The Discovery of quarks meant that protons and neutrons weren’t fundamental anymore. To better understand this, let’s peel apart a piece of matter and discover its constituents by removing each layer one by one.
Is a quark smaller than a Planck length?
The size of a quark compared to plank length is multitudes larger than plank length. For comparison, if the quark was the size of the sun, the plank length would be the size of a grain of sand.
What is the smallest possible photon energy?
The smallest energy photon possible is the size of the universe. A photon with half the energy is twice the size and cannot propagate in a smaller space. The Plank energy, 1.96 × 10-9 Joules, is the maximum energy a photon can have.
What is the longest and smallest wavelength of light?
Possibly the longest wavelength of light can be associated with a zero-point energy, but the smallest wavelength of light is associated with the highest energy possible in one photon. These are probably limited by Quantum Mechanics, though I’m not sure.
What is the size of the smallest features we can see?
In a microscope, the size of the smallest features we can see is limited by the wavelength used. With visible light, the smallest wavelength is 400 nm = 4 x 10 -7 m. Typical electron microscopes use wavelengths 1000 times smaller and can be used to study very fine details.
What is the minimum size of an electromagnetic wave?
Seems like in principle, there should be no minimum size. For example, a small hand-held radio (cell phone for those of you in the 21st century) can detect, generate, and scatter EM waves with wavelength much longer than the object itself.
How is the wavelength of light related to the momentum?
And also reasoned that matter would follow the same equation for wavelength as light namely, Where p is the linear momentum, as shown by Einstein. de Broglie derived the above relationship as follows: 1) E = hν for a photon and λν = c for an electromagnetic wave. 2) E = mc 2, means λ = h/mc, which is equivalent to λ = h/p.
