**Wave nature of light**

– Proof: light undergoes interference

– Light propagates as an interdependent combination of electric and

magnetic fields, each oscillating with a wavelength lambda, a

frequency f and a speed c such that $c = f \lambda$

Particulate nature of light

– Energy is quantized and exists in discrete packets or quanta. Each

quantum of light is called a photon.

– Proof: Compton’s scattering

Wave property of matter (need eqn)

– Proof: Electron diffraction

Principle of complementarity

– The wave and particle models are complementary; if a measurement

proves the wave character of radiation or matter, then it is

impossible to prove the particle character in the same measurement,

and vice versa.

I feel that this is a nice video:
