Physics 5 — Modern Physics
Matter waves
continues from lesson 2 — values defined earlier in the course stay live here
De Broglie's symmetric heresy: if waves are particles, particles are waves, with λ = h/(m·v). An electron's wavelength is atom-sized — that's why electron microscopes see what light cannot:
electron mass (kg)
a typical microscope beam (m/s)
= ~0.36 nm — sharper than any light
