Chapter 35 321 Method Two: The vector velocity of the incident light has a component v y perpendicular to the first mirror and a component v x perpendicular to the second. The v y component is reversed upon the first reflection, which leaves v x unchanged. The second reflection reverses v x and leaves v y unchanged. The doubly reflected ray then has velocity opposite to the incident ray. (b) The incident ray has velocity vvv xyz ±±± ijk ++ . Each reflection reverses one component and leaves the other two unchanged. After all the reflections, the light has velocity −−− , opposite to the incident ray.
