29.5 The Particle-Wave Duality
Unrounded values are used in all calculations to avoid rounding errors and an expected verification of the relationship.
The relationship between energy, momentum, and mass given by applies to both matter and photons.
Even when is, note that is not zero.
The forms of the constants may be useful for this section.
We have known for a long time that EM radiation can cause interference.
Massless particles can be modeled as light.
This may seem odd since we usually deal with large objects that don't act like particles.
An ocean wave is not like a rock.
We make analogies with the large-scale phenomena we observe directly.
When we say something behaves like a wave, we mean it shows interference effects similar to those seen in water waves.
There are two examples of waves.
When we say something behaves like a particle, we mean that it interacts as a unit with no interference effects.
There are particles in the radiation.
The properties of wavelength and Frequency are affected by EM radiation.
There is no doubt that it behaves as particles.
The properties of the photon are similar to the phenomena we can observe directly.
We don't ordinarily observe details on the quantum level directly, and our observations yield either particle or wavelike properties, but never both at the same time.
