Can photons occupy the same space?

Theoretically, since photons are not subject to the Pauli exclusion principle , there is no limit on the amount of photons that could occupy the same space.

Does a single photon spread out?

A single photon is naturally spread out and does so in the same way as a wave. Never-the-less when it interacts all the energy it has will be involved in the interaction at one location (as a classical particle).

What happens when a photon hits another photon?

If two photons head towards each other and they both turn into electron/anti-electron pairs at about the same time, then these particles can interact. The anti-electron from one photon will collide with an electron from the other photon, and turn back to light.

Do light particles take up space?

Photons, the particles that make up light, are massless, but does that mean they don’t take up space? They are 0-dimensional particles (1D if string theory is correct), so it’s hard to imagine them taking up space, but everything in the universe is made of 0-dimensional particles, and they take up space.

Can two things occupy the same space at the same time?

The laws of physics say that two objects cannot occupy the same space at the same time. Waves are not objects. Waves can and do occupy the same space at the same time – in other words, they interfere with each other.

How far do photons travel?

But for light itself, which is already moving at light speed… You guessed it, the photons reach zero distance and zero time. Photons can take hundreds of thousands of years to travel from the core of the Sun until they reach the surface and fly off into space.

Are there gaps between photons?

There are no gaps in space between the photons as they travel. A rough but helpful way to look at photons is that they act like waves while traveling and act like particles when interacting with matter.

What particles make up a photon?

The photon belongs to the class of bosons. Like all elementary particles, photons are currently best explained by quantum mechanics and exhibit wave–particle duality, their behavior featuring properties of both waves and particles….Photon.

Photons are emitted in threaded laser beams
Composition	Elementary particle
Symbol	γ

How do Photons differ from each other?

Photons have one extra parameter that can distinguish them from each other and it’s the amount of energy they’re carrying. This energy corresponds to the color of the light – the more energy, the further to the blue the light appears, and the less energy, the harder to the red it falls.

How long does it take a photon to travel through the Sun?

To send us this photon must traverse the various layers of the Sun. The transit time of a photon of the heart at the surface is between 10 000 and 170 000 years based on collisions.

What is the momentum of a photon in empty space?

In empty space, the photon moves at c (the speed of light) and its energy and momentum are related by E = pc, where p is the magnitude of the momentum vector p. This derives from the following relativistic relation, with m = 0:

How many possible polarization states does a photon have?

A photon has two possible polarization states. In the momentum representation of the photon, which is preferred in quantum field theory, a photon is described by its wave vector, which determines its wavelength λ and its direction of propagation.
