Hello
I red in web side " The photon has mass " Is that real ?
and what about
m = h / lamda * c

Photon mass refers to the theoretical mass of a photon, which is a type of elementary particle that makes up light. It is usually denoted by the symbol “m” and is measured in units of energy divided by the speed of light squared (E/c^2).
The formula for calculating photon mass is h/(lambda*c), where h is the Planck constant, lambda is the wavelength of the photon, and c is the speed of light. This formula is derived from Einstein’s famous equation E=mc^2, where E is energy and m is mass. By rearranging the equation, we can solve for the mass of a photon.
No, photon mass is not a constant value. According to Einstein’s theory of relativity, the mass of a particle is not a fixed quantity, but rather depends on its speed. Since photons travel at the speed of light, their mass is constantly changing and can be considered negligible in most cases.
The photon mass equation, h/(lambda*c), is significant in understanding the fundamental properties of light and its behavior. It allows us to calculate the mass of a photon and shows the relationship between energy, mass, and the speed of light. It also helps to explain phenomena such as the photoelectric effect and the creation of matter and antimatter pairs.
No, photon mass cannot be directly measured as it is considered to be negligible. However, scientists can indirectly measure the effects of photon mass through experiments and observations, such as the bending of light in a gravitational field. These measurements help to confirm the validity of the concept of photon mass.
