Unformatted text preview: ) We have looked at interference due to sources separated in space. What about the time component of a wave? Sources separated in frequency? Interference of 30 0 Hz 31Hz (Beats) 30 Hz and 31 Hz 3 Hz and At fixed position, Beat is difference average Dispersion In materials, the angular frequency is a function of the wavenumber, The phase velocity, the velocity at which the waves propagate, / The group velocity, the velocity at which the modulation or wave packet propagates, Speed at which information propagates : 1 A...
