Describing a photon with it’s particle and wave properties have been found to be useful. Even a large object like the Earth exhibits wave properties, for instance you’re body has an equivalent wavelength. I use to consider light as a particle and a wave. However I later moved on to describe a...
This misunderstanding seems to be due to the way the formula was shown E=hv. It’s easier to recognize if you write E=hf where E is the energy in joules, h is hertz constant, and f is frequency cycles per second. Hope this helps, I suggest you read on valence jumps. It will make things more...
