    Answer:

    diffraction phenomenon

    Explanation:

    When you place your finger in front of a flash, you have a diffraction phenomenon whereby the light fills a part of the space with the first maximum diffraction.

    In this case the phenomenon of geometric optics cannot explain the process of bending the beam around an object.
