Do photons change size?

A photon is a massless “particle”, and an infinite number of massless particles can occupy the same space. Hence, size is meaningless for a photon and all massless particles.

What is the size of a single photon?

A photon is in shape like a thin stick if its energy is lower than the rest energy of an electron and like a plate if its radius is smaller than the classical radius of an electron. For a photon of hν=13.6 eV, the photon radius is 34.9 pm and is less than the Bohr radius.

What happens when the wavelength of a photon increases?

All photons travel at the speed of light. From this equation, it is clear that the energy of a photon is directly proportional to its frequency and inversely proportional to its wavelength. Thus as frequency increases (with a corresponding decrease in wavelength), the photon energy increases and visa versa.

How does wavelength relate to size?

There are several interactions occuring (radiation, quantum etc), but one thing that can be said is that the size of the particles influences the wavelength of light scattered. Larger particles scatter a greater range of wavelengths of light.

Does a single photon have a wavelength?

Generally speaking, photons have similar properties to electromagnetic waves. Each photon has a wavelength and a frequency. The wavelength is defined as the distance between two peaks of the electric field with the same vector.

What is length of photon?

The length of a photon could reasonably be measured as the maximum difference in the paths between the two paths in a 2 slit (Young’s slits) experiment before there is no observed interference pattern.

What happens when the wavelength of light is changed?

Wave speed, frequency and wavelength in refraction Although the wave slows down, its frequency remains the same, due to the fact that its wavelength is shorter. When waves travel from one medium to another the frequency never changes. The wave is slower but the wavelength is shorter meaning frequency remains the same.

Do photons have a wavelength?

Generally speaking, photons have similar properties to electromagnetic waves. Each photon has a wavelength and a frequency. The wavelength is defined as the distance between two peaks of the electric field with the same vector. Unlike an electromagnetic wave, a photon cannot actually be of a color.

Does Size Affect wavelength?

The scattering of light and the color of the scattered light depends upon the size of the particles. Smaller particles scatter the light of shorter wavelength, like blue and violet and larger particles scatter longer wavelength like, red and orange.

What is one use of a wave that has a wavelength about the size of an atom?

X-rays have a similar wavelength to the size of a water molecule. Because X-rays are about the same size as atoms, they are often used to determine the position or arrangement of atoms in solids.

What is the wavelength of one photon?

The photon is an elementary particle in the standard model of particle physics. It does not have a wavelength. It is characterized in the table as a point particle with mass zero and spin one.
