This video introduces coherence and
This video introduces coherence and its relationship with path difference for A Level Physics.
Coherence, path difference and phase difference are really important subjects to consider when we look at the interference of waves and how this leads onto double slit and diffraction grating patterns (to see how these work please look at these videos: http://bit.ly/1GQ5yEi and http://bit.ly/1Fmf2Wc). Coherence is a special case of interference (coherent waves interference).
DEFINITION OF COHERENT WAVES IS THAT THEY HAVE A CONSTANT PHASE DIFFERENCE.
Thanks for watching,
