Can you change the frequency of a photon?

The photon remains intact – that means only its frequency changes. A process that consumes one photon and produces another at a different frequency.

Can the frequency of light be changed?

Frequency of light does not ever change, as long as you can be sure that the photons are the same as the photons at the beginning. Wavelength L is, on the other hand, tied with energy through its speed, E=hf=hv/L .

What affects the frequency of a photon?

The amount of energy is directly proportional to the photon’s electromagnetic frequency and thus, equivalently, is inversely proportional to the wavelength. The higher the photon’s frequency, the higher its energy. Equivalently, the longer the photon’s wavelength, the lower its energy.

Why frequency of photon does not change?

C. Frequency. If there is change in the energy of the photon, then only the frequency will change and if there is no change in energy, then the frequency remains constant.

What decreases the frequency of light?

If we increase the temperature of the body emitting light, then the wavelength will decrease. Since speed of light is constant and wavelength decreases, frequency would obviously increase. Increasing the temperature of the source body will increase frequency of light.

Can you change the wavelength of light?

The wavelength of light can be changed if the light is first absorbed by electrons of a substance to put them into an excited energy state. When the electrons returns to their ground state they will emit light of the particular wavelength corresponding to the energy difference between the two states.

How can you increase the frequency of a photon?

There is a general way to increase the frequency of light. It is Doppler Effect. You can keep the observer (target for photoelectrons) and move the source of light towards it. But it is not practical, because you will need very high relative velocity to have any considerable change in the frequency.

How do photons move?

A photon is a pulse of an electric field which when it collapses produces a magnetic field which when it collapses produces an electric field and so on and on until either the electric field and/or the magnetic field is absorbed by something. In other words the photon propagates itself thus moving away from the source.

How do you change the frequency of light?

Why does frequency remain unchanged?

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. As waves travel into the denser medium, they slow down and wavelength decreases.
