What happens when a photon of light hits an atom?
When an electron is hit by a photon of light, it absorbs the quanta of energy the photon was carrying and moves to a higher energy state. Electrons therefore have to jump around within the atom as they either gain or lose energy.
What happens to the photons of light when they come in contact with the atoms of the reflective surface?
A photon will be absorbed if its energy, given by E=hν, fits some energy level of the atoms, (molecules, system) it hits and then a re-emitted photon may change both direction and energy with respect to the originating one, i.e. if the reflected one changes frequency because of the re-emission,and loses the phase it …
What happens when light photons collide?
However, two photons heading towards each other can indeed collide indirectly. A photon can spontaneously degenerate into a particle with mass and its antiparticle in a process known as pair production. In this process, the energy of the photon is completely transformed into the mass of the two particles.
Why are photons released from atoms?
When the electron changes levels, it decreases energy and the atom emits photons. The photon is emitted with the electron moving from a higher energy level to a lower energy level. The energy of the photon is the exact energy that is lost by the electron moving to its lower energy level.
How does a photon reflect?
According to Newton’s third law, for every action(force) there is always an equal reaction. Therefore, whenever a photon strikes a surface then it strikes with a force. Then an equal magnitude of reaction is also seen but the kinetic energy reduces after the strike. This is the process by which a photon reflects!
What happens to light when it hits an object?
When light hits an object, it is transmitted, absorbed, and/or reflected. The light on the left is reflected, the light in the middle is absorbed and the light on the right is transmitted. Any object you can see must at least partially reflect light to your eyes. Objects can ALSO absorb and/or transmit light.
