Bending of light into regoins of geometrical shadow is called:

The penetration of waves into the region of geometrical shadow is due to

Assertion : If we look clearly at the shadow cast by an opaque object, close to the region of geometrical shadow, alternate dark and bright regions can be seen. Reason : This happens due to the phenomenon of interference.
