In my physics notes it is stated that the light phase changes every 10^-8 seconds, hence light from 2 light original light sources. I understand how light from incoherent light doesn't allow for diffraction but by what physical mechanism does the light undergo phase changes at that rate?

    $\begingroup$ That's not a general rule. The coherence time depends on the source. Your notes must have a particular source in mind. Without knowing the type of source, not much can be said (other than guesses). $\endgroup$ – garyp Mar 26 '18 at 2:25
