Light before Quantum Theory
Light: Wave or particle?
We have now arrived at a dilemma.† We donít know exactly what Light is, or what the nature of Light is.† We can explain the phenomenons of Light sometimes with the wave theory, sometimes with the quantum theory, and in some cases, such as Light propagation, both theories are valid.† But if this is so, what is Light?
What happens is that Light behaviour is like a wave for itís propagation meanwhile it has a particle character when it interacts with the matter.
The question of whether Light is a wave or a particle is still being debated.
