How does a photon move.If it is a particle and moves in a straight line,what do we mean by its frequency in
E=hf?
E=hf?
No one actually knows since we can't observe a photon without destroying it (i.e. in a photodetector). I'm sure this has been discussed somewhere recently, I'll have a dig around later and see what I can find.anantchowdhary said:How does a photon move.
The frequency is simply the frequency of the EM field oscillations, which determines the properties of light.anantchowdhary said:it is a particle and moves in a straight line,what do we mean by its frequency in

The equation E=hf represents the relationship between the energy (E) of a photon and its frequency (f). This equation is known as the Planck-Einstein relation, and it explains how the energy of a photon is directly proportional to its frequency. Essentially, the higher the frequency of a photon, the higher its energy will be.
The concept of wave-particle duality states that particles, such as photons, can exhibit both wave-like and particle-like behaviors. In the case of photons, they exhibit wave-like behavior in terms of their frequency, wavelength, and interference patterns, while also behaving as discrete particles in terms of their energy and momentum. This duality helps to explain the motion of photons and their interaction with matter.
The Planck constant (h) is a fundamental constant in physics that relates the energy of a photon to its frequency. In other words, it provides a numerical value for the proportionality constant in the equation E=hf. This constant is crucial in understanding the behavior of photons and how they interact with matter.
The equation E=hf is used in various practical applications, such as in the development of laser technology, solar cells, and other devices that utilize the energy of photons. It also plays a significant role in understanding the behavior of light in various fields, including astronomy, telecommunications, and medical imaging.
While the equation E=hf is a fundamental relationship that helps to explain the behavior of photons, it does have its limitations. It does not take into account the effects of relativity or the wave-like behavior of photons in certain situations. Additionally, it is not applicable to particles other than photons, as they have different relationships between energy and frequency.
