How reflection and refraction of light expressed at the particles level ?
Thanks in advance
Thanks in advance

after photons hit the matter subatomic particles ?
But the effect of a solid or liquid medium on the direction of light does not involve just one photon and one atom. IF you really want to discuss refraction in terms of photons, then you have to consider the interaction of individual photons with the whole structure. (i.e. you cannot talk in terms of a photon, like a little bullet, hitting a specific part of the surface; it has to be considered as if it could be everywhere over a large region. This is a good reason for solving such problems in terms of waves! Neither approach is any more or less valid for describing EM radiation so why not choose the most convenient one?DEvens said:When a photon strikes an atom, etc.,
Reflection is the bouncing back of light particles when they hit a smooth and shiny surface, while refraction is the bending of light particles as they pass through a medium with different optical density.
The properties of particles, such as their size, shape, and density, can affect the way light is reflected or refracted. For example, larger particles may reflect more light while denser particles may cause more refraction.
The angle of incidence, which is the angle at which light hits a surface, determines the angle at which light will be reflected or refracted. The greater the angle of incidence, the greater the angle of reflection or refraction will be.
Yes, particles can affect the color of reflected or refracted light. This is due to the phenomenon of selective absorption, where certain particles will selectively absorb and reflect certain wavelengths of light, resulting in a change in color.
The speed of light changes during reflection and refraction at the particle level because the particles in a medium can slow down the speed of light. This is why light appears to slow down and bend when passing through a denser medium, such as water or glass.
