Particles can't have wave properties. Waves can't have particle properties. The position of a particle always can be exactly known. A photon is a particle with a wave inside. Photons of higher frequency are bigger than photons of lower frequency.
All photons have the same energy.
Intensity means that the amplitude of a photon is bigger. The Uncertainty Principle results from the limits of measuring devices. Laser beams are always visible by themselves. Sometimes you feel like a wave, sometimes you don't. There is only one correct model of the atom.
