What causes a reflection of light?

Reflection of light (and other forms of electromagnetic radiation) occurs when the waves encounter a surface or other boundary that does not absorb the energy of the radiation and bounces the waves away from the surface.

Is the reflection of light by particles?

Light emitted by a source, whether near or far, arrives at the mirror surface as a stream of particles, which bounce away or are reflected from the smooth surface. However, the particle theory also suggests that if the surface is very rough, the particles bounce away at a variety of angles, scattering the light.

What are the effects of reflection of light?

Answer: According to the undulatory theory of light the velocity of light is independent of the velocity of the source, and of the velocity of a mirror at which it is reflected. According to the emission theory the resultant velocity from a moving source is increased by the component of the velocity of the source.

How are reflection and refraction explained by the particle?

The case for a particle nature for light is far stronger with regards to the reflection phenomenon than it is for refraction. Upon impacting the mirror, the particles bounce from different points, so their order in the light beam is reversed upon reflection to produce a reversed image, as demonstrated in Figure 4.

What is meant by reflection of light?

Reflection is when light bounces off an object. If the surface is smooth and shiny, like glass, water or polished metal, the light will reflect at the same angle as it hit the surface. For a smooth surface, reflected light rays travel in the same direction. This is called specular reflection.

What happens to photons when they are reflected from a metal?

The photons of the light reflected from a metal (or a dielectric mirror) are identical to the incident ones, apart from the changed propagation direction. The loss of light in the metal means that some fraction of the photons are lost, while the energy content of each reflected photon is fully preserved.

What happens to the light that is reflected from a mirror?

Visible white light that is directed onto the surface of a mirror at an angle (incident) is reflected back into space by the mirror surface at another angle (reflected) that is equal to the incident angle, as presented for the action of a beam of light from a flashlight on a smooth, flat mirror in Figure 2.

What is the difference between metallic reflection and non-metallic reflection?

The reverse photon energy radiates and rejoins the parallel energy component of the photon and reconstructs the photon, bouncing off with the angle bisected by the normal to the surface. § The difference between the metallic reflection and non-metallic reflection is that at all angles of incidence the photon reflects well from the metal.

What causes the mirror effect in quantum mechanics?

This effect is related to tiny wavelength-dependent time delays that light experiences in the mirror structure. In a quantum-mechanical picture, light consists of photons, or packages of optical energy.
