PPT-Diffraction of Light By definition, diffraction refers to the apparent bending of waves

Diffraction of Light Newton pointed out in his 1704 book Opticks that Light is never known to follow crooked passages nor to bend into the shadow This concept is consistent with the particle theory which proposes that light particles must always travel in straight lines.
