If a parallel beam of light falls on a plane mirror it is reflected as a parallet beam ,Figure 2.5a,and regular reflection occure .Most surfaces ,however ,reflect light irregularly and the rays in an incident parallel beam are reflected in many directions,Figure 2.5b

如果一束平行光照射到镜面上,它的反射光也是平行光,这个Figure 2.5a应该是“如图2.5a”所示,你可能是从书上抄的吧.继续,后面的意思是:我们管这个叫做镜面反射(直译叫“规则反射”).但是大多数的表面并不是规则的反射平行光,平行光被反射后有可能朝着各个方向继续传播,如图2.5b所示
呵呵,应该是这个意思啦~
