    Answer:

    Angle of incidence = angle of reflection = 0

    Explanation:

    Given that,

    A light beam strikes a shiny object at a 90-degree angle.

    The angle made by incident ray and normal to the mirror is called the angle of incidence and the angle made by the reflected ray and the normal is called the angle of reflection.

    Here, the beam strikes normally. So, the angle of incidence is 0.

    A/c to the law of reflection,

    Angle of incidence = angle of reflection

    So, the angle of reflection is also equal to 0.
