    1) Diffraction is a result of reflection or interference?
    2) angle of reflection is _same __ as the incident angle?
    :confused:

    If the angle of reflection is the same as the critical angle then through a prism, most of the light will go along the straight edge and a little will be refraceted out with a little tir.

    (1) Diffraction is the spreading out of light (or other waves) after encountering an obstacle or passing through an aperture. It can be understood as a consequence of interference.

    (2) The law of reflection states that the angle of incidence equals the angle of reflection. Note that these angles are measured from a line normal (perpendicular) to the reflecting surface.
