| Can the mass of light be calculated? The
Heisenberg Uncertainty principle states that it can't, since when ever
something is measured it is changed. Thus the conclusion is that light
has two properties. It has a wave property that is separate from its
particle property. It does two things at once. Therefore this
definition means the particle is not a characteristic of the wave and
the wave is not a characteristic of the particle. How can mass be calculated? According to Newton: For every action there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object. F=MA (Force equals mass times acceleration) Thus, the mass of the photon can be calculated. I encourage the reader to solve this mathematical problem.
The mass of an electron is 9.109 382 15(45) × 10–31 kg[1] To move an electron it will take at least the mass of an electron to move it from one place to another based on Newton's third law. So, when enough sunlight (energy) is absorbed by the material (a semiconductor), electrons are dislodged from the material's atoms. These electrons do not move on their own, they must be pushed. Thus Newton's third law comes into play. This is significant, because it shows that the wave could be proven to be a characteristic of the particle.
