The Motion of Photons: Where Does the Energy Go?

In summary, a photon is energy in motion. When it collides with an object, such as the eye, its energy and momentum are passed on and may cause a chemical reaction. The photon does not come to a complete rest, but rather no longer exists after its energy has been absorbed.

It is my understanding that a photon is essentially energy in motion. However, if by example, I were to shoot a photon in the form of light, at someones eye. Where does the photon go, once it reaches a rest position after colliding with the eye?

1. Is the energy that makes this photon, simply destroyed once it reaches a rest position?
2. Where does it go?

Energy cannot be destroyed. The energy and momentum of the photon are passed on and may stimulate a chemical reaction ( for instance).

Also the photon does not "come to rest". Is simply no longer exists after the photon's energy has been absorbed into a body.
 

FAQ: The Motion of Photons: Where Does the Energy Go?

What is the concept of the motion of photons?

The motion of photons refers to the movement of electromagnetic radiation, which can be described as waves or particles called photons. This motion is the basis for many scientific theories, including the theory of relativity and quantum mechanics.

What happens to the energy of photons when they are emitted?

When photons are emitted, the energy they carry is transferred from the source to the surrounding environment. This can occur through various mechanisms, such as absorption, reflection, or scattering.

Where does the energy of photons go when they are absorbed?

When photons are absorbed, their energy is transferred to the absorbing material. This can result in various effects, such as heating the material or causing chemical reactions.

Can the energy of photons be transferred between different forms?

Yes, the energy of photons can be transferred between different forms, such as from electromagnetic radiation to heat or from visible light to chemical energy in photosynthesis. This is due to the dual nature of photons as both waves and particles.

How is the energy of photons related to their wavelength and frequency?

The energy of photons is directly proportional to their frequency and inversely proportional to their wavelength. This relationship is described by the equation E=hf, where E is energy, h is Planck's constant, and f is frequency. This means that photons with higher frequencies have more energy than those with lower frequencies.
