光子具有动量,每个光子的动量mv=h/λ式中h为普朗克常量,又为光子的波长).当光照射到物体表面上时,不论光被物体吸收还是被物体表面反射,光子的动量都会发生改变,因而对物体表面产生一种压力,称为光压.图是列别捷夫设计的用来测量光压的仪器.图中两个圆片中,a是涂黑的,而b是光亮的、当光线照射到a上时,可以认为光子全部被吸收,而当光线照射到b上时,可以认为光子全部被反射.分别用光线照射在a或b上,由于光压的作用,都可以引起悬丝的旋转,旋转的角度可以借助于和悬丝一起旋转的 * * 面镜M进行观察.

(1)如果用两束光强相同的光同时分别照射两个圆片a、b,光线的入射方向都跟圆片表面垂直,悬丝将向哪个方向偏转?为什么?

(2)己知两个圆片a、b的半径都为r,两圆心间的距离是d,现用频率为ν的激光束同时照射a、b两个圆片,设入射光与圆面垂直,单位时间内垂直于光传播方向的单位面积上通过的光子个数为n,光速为c,求:由于光压而产生的作用力分别是多大.
