N the smallest possible angle of incidence for which light rays are totally reflected at an interface between substances of different refractive index 临界角
So it's past the critical angle; the angle is smaller.
它超过了临界角;,角度变小。
but remember, we set it at the critical angle, so that cotangent alpha is 2 mu.
,但是记住，摆放的恰是临界角，所以cotα等于2μ
At all angles less than the critical Angle, both reflection and refraction occur.
对于所有小于临界角的入射角，则既发生反射，又发生折射。
