    a) 40 degrees

    When a light wave reflects off a mirror, it must obey the

    law of reflection - angle of incidence is equal to angle of reflection.

    If the angle of incidence is 40 degrees, the angle of reflection is 40

    b) 50 degrees

    incident angle = reflected angle BUT grazing angle is given as 40 so incident angle taken from the normal at right angles to the mirror is 50
