(a) State any two fundamental postulates that led to the concept of matter waves.
(b) Explain how the known energy–momentum relation for photons suggested a similar wavelength–momentum relation for material particles.
(c) Distinguish between the wave nature and particle nature of electrons, quoting one experimental observation for each aspect (description only, no experimental details required).
