Photo energy wavelength
WebOrdinary particles have a wavelength so small that we can't see the oscillations (this is because ordinary particles have mass). Photons, on the other hand, do not have mass. Their nonexistent mass and high speed (speed of light, c) cancel out nicely to produce noticeable wave like behavior.
