How can a photon have a frequency?

How can a photon have a frequency?

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. The frequency of a photon is defined as how many wavelengths a photon propagates each second. Instead, a photon will correspond to light of a given color.

Can a photon have no frequency?

No, sometimes photons exhibit properties of a particle, and other times it exhibits properties of a wave, therefore having a “frequency” and at the same time being a particle.

In which phenomenon photons are in phase?

Stimulated emission occurs when matter in an excited state is perturbed by a photon of light and gives rise to a further photon of light, typically at the same energy and phase as the perturbing photon….What is Light Emission.

Can there exist a single photon that is white light?

You cannot have a single photon of white light. If you have a very dim white light source, which produces only one photon at a time, you will never see a “white” photon. You will, however, see photons of all different colors, as all those colors combined create the color white as seen by the human eye.

Do photons have phase?

While the phase of a coherent light field can be precisely known, the phase of the individual photons that create this field, considered individually, cannot. In fact, actively controlling the phase of individual photons has been identified as a powerful resource for quantum communication protocols.

Which is the relationship between photon energy and frequency?

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.

Why does light have different frequencies?

Light waves also come in many frequencies. The amount of energy in a light wave is proportionally related to its frequency: High frequency light has high energy; low frequency light has low energy. So, gamma rays have the most energy (part of what makes them so dangerous to humans), and radio waves have the least.

Which of the following are characteristics of photon has have?

Photons have no mass but they have energy. E=hv where h is the planks constant. The energy of each photon is inversely proportional to the wavelength of the associated EM wave.

Is a photon a single frequency?

Even a single bit of light (a photon) never has exactly one frequency. It is fundamentally impossible for a photon to have exactly one frequency. Certain beams of light, such as laser beams, can get very close to having one frequency, but can never have exactly one frequency.

What is the frequency of black color?

Or, put another way, the frequency is zero. Blackness is the absence of light, so turning on a light of any visible frequency would mean that you don’t have black. White is a mixture of all frequencies; black is no frequency.

Are photons harmonic oscillators?

Photons interact with each other like waves. Since the modes of an electromagnetic field have the same classical equations as a simple harmonic oscillator, a photon can and is modeled as a simple harmonic oscillator, where the energy of the photon is proportional to the frequency of the photon.
