PHYS 1061 Lecture Notes - Lecture 33: Photon, Diffraction Grating, Visible Spectrum
Document Summary
Look at bright, uniform source through tiniest pinhole you can make you"ll see slowly moving specks with rings around them diffraction rings: shadow between thumb and forefinger. Appears to connect before actual touch: streaked street-lights through windshield. Point toward center of wiper arc: diffraction grating formed by micro- Consider the fact that they also pile up in the middle! Pure ballistic particles would land in one of two spots: (cid:1)(cid:2)(cid:3)(cid:4)(cid:5)(cid:6)(cid:7)(cid:5)(cid:8)(cid:2)(cid:7)(cid:9)(cid:10)(cid:11)(cid:12)(cid:4)(cid:13)(cid:5)(cid:14)(cid:4)(cid:10)(cid:9)(cid:15)(cid:4)(cid:7)(cid:16)(cid:5)(cid:17)(cid:6)(cid:9)(cid:15)(cid:16)(cid:5)(cid:9)(cid:2)(cid:18)(cid:4)(cid:5)(cid:19)(cid:6)(cid:20)(cid:7)(cid:5)(cid:21)(cid:10)(cid:11)(cid:18, non-intuitive combination of wavelike and particle-like, appears to behave in wavelike manner. But with low intensity, see the: how does the photon know about the other slit? interference pattern build up out of individual photons, arriving one at a time. Actually, it"s impossible to simultaneously observe interference and know. Emergent picture is one of probability distributions describing where electrons can be: probability distributions are static. Electron is not thought to whiz around atom: it"s in a stationary state of probability: separate functions describe the radial and angular pattern.
