Chapter 35321Method Two:The vector velocity of the incident light has a component vyperpendicular to the first mirrorand a component vxperpendicular to the second. The vycomponent is reversed upon thefirst reflection, which leaves vxunchanged. The second reflection reverses vxand leaves vyunchanged. The doubly reflected ray then has velocity opposite to the incident ray.(b)The incident ray has velocity vvvxyz±±±ijk++. Each reflection reverses one component andleaves the other two unchanged. After all the reflections, the light has velocity−−−, opposite to the incident ray.P35.8The incident light reaches the left-hand mirror at distance10050000875.tan..m maf°=above its bottom edge.
